Cisco's Question Marks

On Cisco's fourth quarter earnings call earlier this month, Chairman and CEO John Chambers said Cisco was charting a course toward "the next Cisco" -- a leaner company, simpler to do business with and more focused on key technology priorities instead of 30 or more distracting "adjacencies."

Based on all that's happened to Cisco in the past eight months and CRN's ongoing interviews with Cisco observers, here's a look at 10 big questions for the networking titan as its employees, channel partners and customers charge into Cisco's fiscal 2012.

Has Cisco Turned The Corner?

The first question, and the most obvious, concerns Cisco's growth, especially as it lays off 6,500 employees as part of a workforce reduction that'll leave Cisco well north of 12,000 jobs lighter.

Cisco took an expected profit loss during its fourth quarter of 2011, but there were a number of signs that Cisco is beginning to stabilize as it continues a broad corporate restructuring expected to remove $1 billion in expenses during its fiscal year. Specifically, said Chambers, Cisco will be a "very focused, agile, lean and aggressive company," and expects to grow revenue between 1 percent and 4 percent in the first quarter.

Cisco COO Gary Moore offered another stat that bears watching for partners. Moore said that thanks to Cisco's restructuring, deal approval time has been reduced by more than 65 percent, which was also translating to higher conversion rates and higher win rates for Cisco. It'll take a few quarters to determine whether all of Cisco's cuts mean a simpler, smoother Cisco.

How Will Cisco Defend The Crown?

Cisco may be starting to stabilize, but don't bet that any of its major competitors have lost their taste for Cisco blood, especially after Cisco spent so much of calendar 2011 playing defense. HP isn't the only company touting market share gains against Cisco, and smaller players, like Juniper and Brocade, continue to attack Cisco's bases with relish.

The other new factor? Thousands of Cisco employees -- no small number of them VP-level veterans -- have left the company following Cisco's restructuring. CRN interviews with sources inside Juniper, Huawei Symantec, HP, ShoreTel, Arista Networks and many others -- not to mention several VARs -- have all confirmed the same thing: hiring managers' desks are piled high with Cisco-dappled resumes. Will all that veteran, departed Cisco talent come back to haunt the networking king?

What's The Meat Behind 'Partner-Led'?

Cisco's corporate restructuring has meant a number of changes specific to its Worldwide Partner Organization (WWPO), including the appointments of new channel-facing executives, and departures of others.

It also meant the move to a new strategy called "partner-led," which will theoretically mean a greater emphasis on sales of Cisco products and services through channel partners in all but Cisco's most strategic accounts. Cisco partners, by and large, like the sound of partner-led but most have told CRN the strategy needs clarity: less concept, they say, more brass tacks, cleanly described sales engagement terms.

How Will Cisco's Channel Incentive Programs Evolve?

Cisco in mid-August confirmed changes to its major channel incentive programs, notably the Value Incentive Program (VIP), which in its 18th installment will see some fatter rewards for particular Cisco VARs, and the Teaming Incentive Program (SIP), which finally rolled out in the U.S. more than a year after its debut. The changes mean that one of partners' biggest fears heading into Cisco's fiscal 2012 -- that Cisco would make big cuts to the budget it allocates to the incentive programs -- appears to have been laid to rest.

But look closer, and there are more curious questions. Ricardo Moreno, Cisco's senior director, Strategy, Planning & Programs, Worldwide Channels, told CRN that new incentive programs related to Cisco's cloud programs and partner-led initiative are coming. Will those be sweet rewards for partners or end up creating headaches with too many incentive possibilities and too much complexity?

Is Cisco's Video Strategy Settled?

On one hand, video has never been a more pronounced piece of the Cisco portfolio. Cisco has named video as one of its five major focus areas for "the new Cisco," revenue on its collaboration unit grew 11 percent year-over-year in Q4, and Tandberg is now fully integrated into Cisco, more than a year after Cisco closed its $3.3 billion acquisition. The ordering problems that hampered the Tandberg integration earlier this year seem to have ebbed, according to VARs.

On the other hand, Cisco has cut a number of collaboration and video executives and seen several more walk out the door, and consolidated its service provider, enterprise and consumer video efforts under one executive, Marthin De Beer. There's also the small matters of two of its major consumer-facing video plays, the now-shuttered Flip and the marginalized Umi home telepresence. Video seems one area where Cisco partners seemingly don't need to worry, but it's also difficult to see things as "settled."

Will Cisco Refocus On Security?

Here's a stat that perhaps hasn't gotten much attention from Cisco observers as others have: Cisco's security product sales declined 8.4 percent from its fiscal 2010 to its fiscal 2011, and declined 21 percent (about $415 million this year versus $526 million last year) in its fiscal fourth quarter on a year-over-year basis.

In an interview with CRN earlier this year, Cisco Chairman and CEO John Chambers said that "security is our number one emphasis across the whole company, mainly because it's our customers' No. 1 issue" and discussed how many security challenges will be solved "in the network." After a year of security declines for Cisco -- and the fact that its ASA appliances were its hardest-hit products during Cisco's 2010 supply chain crisis -- many security-facing solution providers are wondering about Cisco's next move here.

Has Cisco's Acquisition Strategy Changed?

Up through the present, Cisco has been on an acquisitions streak that's gone largely unabated since 1993 -- indeed, it's one of the industry's most voracious acquirers.

What'll be interesting is whether this year's emphasis on Cisco's restructuring means any slowdown in acquisitions overall. Cisco bought three companies already this year, including cloud provisioning specialist NewScale, but it's vowed to become a simpler company, and less distracted by new "adjacencies" to which some acquisitions can provide it access.

Is Cisco Cius A Tablet Contender?

Cisco is looking to position Cius, its Android-based tablet, as the ultimate in business-centric endpoints for full-fledged enterprise unified communications systems.

Cisco finally launched the Cius globally at the end of July, and with volume discount programs, the Cius' price should be about $650, not including the additional price of its docking station. Is the market ready to embrace Cius, however, when so much of Cius' charm depends on its use with Cisco's own equipment and services, and there's so much competition in the tablet market in general? Cisco has been steadfast in positioning Cius as having business-centric features, such as on-board security, that separate it from Apple's iPad, but with iPad itself penetrating the enterprise and so much eardrum-shattering hype around tablets, Cisco may have a harder time directing the conversation than it first thought.

Is VCE Solid?

More than a few VARs have reported myriad problems and logistical headaches with VCE, the company that was established as a joint venture of Cisco and EMC with buy-in from VMware and Intel and designed to push the converged data center technologies and private cloud ambitions of all of those vendors.

Rob Lloyd, Cisco's executive vice president, worldwide operations, told CRN in July he is "personally involved" in making VCE simpler and easier for partners to work with, but many questions remain about the venture, which recently opened up to two-tier distribution with Ingram Micro, Arrow and Avnet. EMC recently spoke of "momentum" with VCE in EMC's most exact 10-Q filing, but VCE has also lost millions amid ongoing whispers of internal restructuring.

With all the see-saw chatter, it's tough to get a read on how healthy the VCE venture really is.

Is Cisco Still Focused On Energy?

Because of all the cheerleading Cisco has done for the smart grid and energy management opportunities in exact years, its recent decision to abandon its Network Building Mediator product has gotten more attention than Cisco probably hoped. Gary Moore, Cisco's executive vice president and COO, said on Cisco's Q4 earnings call that Cisco "will no longer be investing in premise energy management devices," a statement that lead to a round of speculation about Cisco's energy market ambitions.

Laura Ipsen, senior vice president and general manager, Cisco Connected Energy Group, said in a corporate blog post that Cisco's "commitment to the industry remains strong and our vision for energy management and Smart Grid has not changed." But for VARs and energy market specialists looking to Cisco as a potential thought leader for next-gen energy management technologies, the move leaves a sour aftertaste.

5 Questions Partners Still Have About The Groundbreaking Apple-Cisco Partnership

Questions Unanswered

Apple and Cisco on Monday announced a blockbuster partnership to more tightly integrate iPhones and iPads with Cisco enterprise collaboration products.

The blockbuster deal signifies another strategic move by Apple to make its devices more appealing to enterprise customers.

"It is in the same vein as making sure the devices that Apple is making are in sync with the application demand of a changing workplace," said Jack Narcotta, an analyst at research firm Technology Business Research.

Partners cheered the new partnership, which will optimize Cisco collaboration tools like Cisco Spark, Cisco Telepresence and Cisco WebEx on iOS devices.

However, some partners still have several unanswered questions surrounding the new partnership. Following are five concerns at the top of Apple and Cisco partners' minds.

(Cisco's John Chambers, left, and Apple's Tim Cook)

5. What Kind Of Security Will We See With This Collaboration?

In a statement, Cisco CEO Chuck Robbins (pictured) said the partnership will enable mobile apps and experiences that enterprises need while meeting requirements for management and security.

On the network side, Cisco has made investments in security, announcing the full integration of its ACI software-defined networking technology with its FirePower intrusion prevention system in April.

However, during the announcement of their partnership, Apple and Cisco failed to talk about how they would integrate security features to meet these enterprise requirements.

4. What Is The Timeline Of The Product Rollout?

Rowan Trollope (pictured), senior vice president and general manager of Cisco's Collaboration Technology Group, said in a Periscope conference about the partnership that Apple and Cisco have been working together for the past 10 months to develop products and services behind the partnership.

However, partners are still left in the dark about when Apple and Cisco's new tightly integrated products for the enterprise will roll out.

3. Will Cisco Have Access To Device Data?

During Trollope's Periscope session, one user asked a question that did not get addressed: whether Cisco will have access to device data, such as contacts and emails, on iPhones or iPads.

The question speaks to partner concerns about how Cisco and Apple will seamlessly collaborate between devices and the network while ensuring security for customers.

"I'm just curious how the collaboration between Cisco and iOS is going to be seamless for enterprise applications," said Rick Jordan, director of mobility sales at Tenet Computer Group, a Toronto-based Apple and Cisco partner.

2. Will There Be Future Projects With Apple?

Cisco and Apple remained mum on any future projects between the two companies could arise from the partnership.

According to Trollope, Cisco and Apple will soon begin meeting with business leaders to discuss their technology needs in order to gain a better sense of what products they will jointly develop.

Apple may discuss the partnership and other collaborations between the two companies at its Sept. 9 special event in San Francisco.

1. What Does This Partnership Mean For The Channel?

A top concern for Cisco and Apple resellers is what the new partnership will mean for both companies' channel ecosystems.

The partnership could open opportunities for partners -- particularly those who offer bring-your-own-device solutions -- by optimizing devices in the reseller channel with corporate VoIP networks. However, Apple's partnership with IBM that was announced last year, which enabled iOS apps running on iPhones and iPads to be sold to IBM customers, had some partners feeling left out of the mix.

Bob Venero, CEO of Holbrook, N.Y.-based solution provider Future Tech, an Apple and Cisco partner, said he hopes to hear more details. "As an enterprise VAR, I'm looking forward to somebody at Apple and Cisco reaching out to us to give us details."

Should AI initiatives change network planning?

AI usage will surely drive additional network traffic, but for most enterprises it likely won’t require a major overhaul of the entire data center network.

Everyone is into AI these days, even network planners. But for network professionals, the primary focus has been on the use of AI in network operations. What about the impact of AI on network traffic?

When I asked almost 100 network planners about that, only eight of them told me they've thought about the impact AI might have on network traffic and network plans. Are they missing something? Maybe, because there are two questions on the table here. One is whether AI has a potential impact on enterprise networks and traffic, and the other is whether it could influence technology.

AI's impact on traffic and infrastructure depends largely on enterprise plans to self-host their AI. The great majority of AI models are run on specialized chips like GPUs, which means specialized servers in the data center. As of today, I've gotten comments on "self-hosted" AI from 91 enterprises. I put the term in quotes, because the truth is that only 16 of them actually had been planning in 2023 for specific AI hosting, and only eight said they'd done any self-hosting this year. Not surprisingly, those eight planners are the same eight who've thought about network impact. For 2024, the number jumps to 77, and I think that growth is stimulating interest among both AI and network equipment vendors. Both Cisco and Juniper have been singing about their AI network credentials, for example.

The question, of course, is just what kind of AI is getting self-hosted and networked, and we shouldn't assume we can answer that based on what we're practicing about AI.

Generative AI from players like ChatGPT, Google, and Microsoft is getting a lot of ink, but there is a fundamental problem with the classic generative open-Internet approach as far as businesses are concerned. They're worried about the hallucinations all too common in public-trained chatbots. They're worried about copyright issues biting content that's AI-created. They're worried about the security of their own data if AI is trained in a specialized way. Some are worried about the energy and environmental impact of all those GPUs churning out human-like results. A lot of exact AI initiatives, including Google's Gemini, were advanced in part to push for a new form of generative AI, one that applies the basic large-language-model technology that created popular generative AI services to enterprise data, within enterprise data centers, or as a part of enterprise cloud services.

If enterprises are looking for a kind of lightweight large-language-model approach to AI, that would mean that the number of specialized AI servers in their data center would be limited. Think in terms of a single AI cluster of GPU servers, and you have what enterprises are seeing. The dominant strategy for AI networking inside that cluster is InfiniBand, a superfast, low-latency, technology that's strongly supported by NVIDIA but not particularly popular (or even known) at the enterprise level. NVIDIA's DGX InfiniBand approach is what connects that mass of GPUs in most big AI data centers, which is why there's almost a presumption that InfiniBand will be the technology used for self-hosted AI.

That's probably unnecessary, and possibly downright wrong. Enterprises don't need to crawl the Internet for training data for their model. Enterprises don't need to support mass-market use of their AI, and if they did for applications like chatbots in customer support, they'd likely use cloud hosting not in-house deployment. That means that AI to the enterprise is really a form of enhanced analytics. Widespread use of analytics has influenced data center network planning for access to the databases, and AI would likely increase database access if it's widely used. But even given all of that, there's no reason to think that Ethernet, the dominant data center network technology, wouldn't be fine for AI. So forget the notion of an InfiniBand technology shift. But that doesn't mean that AI won't need to be planned for in the network.

Think of an AI cluster as an enormous virtual user community. It has to collect data from the enterprise repository, all of it, to train and get the latest information to answer user questions. That means it needs a high-performance data path to this data, and that  path can't be allowed to congest other traditional workflows within the network. The issue is acute for enterprises with multiple data centers, multiple complexes of users, because it's likely that they won't want to host AI in every location. If the AI cluster is separated from some applications, databases, and users, then data center interconnect (DCI) paths might have to be augmented to carry the traffic without congestion risk.

According to those eight AI-hosting enterprises, the primary rule for AI traffic is that you want the workflows to be as short as possible, over the fastest connections you have. Pulling or pushing masses of AI data over widespread connections could make it almost impossible to prevent random massive movements of data from interfering with other traffic. It's particularly important to ensure that AI flows don't collide with other high-volume data flows, like conventional analytics and reporting. One approach is to map AI workflows and augment capacity along the path, and the other is to shorten and guide AI workflows by properly placing the AI cluster.

Planning for the AI cluster starts with the association between enterprise AI and business analytics. Analytics uses the same databases that AI would likely use, which means that placing AI where the major analytics applications are hosted would be smart. Remember that this means placing AI where the genuine analytics applications are run, not where the results are formatted for use. Since analytics applications are often run proximate to the location of the major databases, this will put AI in the location most likely to generate the shortest network connections. Run fat Ethernet pipes within the AI cluster and to the database hosts, and you're probably in good shape. But watch AI usage and traffic carefully, particularly if there aren't many controls on who uses it and how much. Rampant, and largely unjustified, use of self-hosted AI was reported by six of the eight enterprises, and that could drive costly network upgrades.

The future of AI networking for enterprises isn't about how AI is run, it's about how it's used, and while AI usage will surely drive additional traffic, it's not going to require swapping out the entire data center network for hundreds of gigabits of Ethernet capacity. What it will require is a better understanding of how AI usage connects with AI data center clusters, cloud resources, and some generative AI thrown in. If Cisco, Juniper, or another vendor can provide that, they can expect a happy bonus in 2024.

What's a tweetchat? Think of it as a webinar in which the speakers, rather than talking, type out their thoughts in 140 characters or less. And instead of a dial-in number, you set your Twitter software (i.e. Hootsuite or my preferred, Tweetdeck) to watch a particular hashtag keyword during the event. (more explanation here)

SAP's Social Media Marketing team will be holding its first tweetchat event on July 28th from 12 noon to 12:30 ET, 9-9:30 AM PT. The hashtag will be, you guessed it, #SAPchat.

SAP's Kevin Cassidy will host. The syllabu will be enterprise mobility, and I'm honored to be one of the two guest (finger quotes) experts, along with Philippe Winthrop of The Enterprise Mobility Foundation.

Philippe is a longtime mobility analyst with IDC and Strategy Analytics - so no finger quotes when I call him a true influencer, especially in the key area of mobile device management (MDM).

Besides MDM, Philippe and I will discuss, among other things:

- what OUR personal forecasts for iPad shipments are this year;

- what it means that nearly 90% of the Fortune 50 have deployed mobile apps;

- whether the tablet market is dividing into several tiers, with focused tablets like the Cisco Cius and the Avaya Flare winning the high-end enterprise category;

- and any and all of your questions.

If you heard the webinar I held with Philippe, Kevin Benedict and FierceWireless' Lynnette Luna several months ago, or follow him at @biz_mobility, you know that Philippe is also an entertaining, opinionated guy. So I promise it'll be a great discussion.

Wed, 03 Jan 2024 22:13:00 -0600 en-us text/html https://www.msn.com/ Cisco uncorks AI-based security assistant to streamline enterprise protection

With Cisco AI Assistant for Security, enterprises can use natural language to discover policies and get rule recommendations, identify misconfigured policies, and simplify complex workflows.

Cisco has unveiled its natural language-based AI Assistant for Security aimed at helping enterprise customers better assess security situations, eliminate configuration errors and automate complex tasks.

The Cisco AI Assistant for Security will first be implemented as part of the vendor's cloud-based Firewall Management Center and Cisco Defense Orchestrator services. Cisco’s Firewall Management Center is a centralized platform for configuring, monitoring, troubleshooting and controlling Cisco Firepower Next-Generation Firewalls. The orchestrator platform lets customers centrally manage, control and automate security policies across multiple cloud-native security systems.

Among the goals of the AI Assistant are to reduce the time it takes for customers to respond to potential threats and simplify the entire security process.

"Using natural language, an administrator can iterate with the AI Assistant to do things like discover and identify all the policies that control access to an application, define a new policy or rule for the administrator, and implement the policy," said Jeetu Patel, executive vice president and general manager of security and collaboration at Cisco, in a blog about the news.

"The AI Assistant can also identify duplicate or misconfigured security policies from amongst thousands of existing policies and make recommendations for resolving them. To me, this is mind-blowing, because this is a level of intelligence that just isn't possible without AI," Patel stated.

In addition, Patel said the security assistant will let customers describe and contextualize events across email, the web, endpoints, and the network to tell security operation center analysts exactly what happened, the impact, and best next steps to take to remediate problems and set new policies.

Cisco first talked about the security assistant at its Live event in June, saying an AI-based assistant will provide easy-to-use situation analysis for network and security teams, correlating intelligence across the Cisco Security Cloud and relaying potential impacts; going forward, customers "won't need to have a Ph.D. to manage a firewall policy," Cisco stated.

In addition to the Assistant, Cisco added a new security feature across its firewall family that lets security teams see into traffic to look for malware without having to decrypt it first. 

"Decrypting traffic for inspection is resource-intensive and fraught with operational, privacy, and compliance issues," Patel stated. With the 7.4.1 Operating System, which is now available, the system can analyze encrypted traffic to identify indicators of malicious behavior that humans can't, and it does so without decrypting, Patel stated.

"For instance, an insulin pump that's running certain operating systems cannot run an end-point client. If it gets attacked by malware that communicates with the outside world via encrypted traffic, you can lose control of the insulin pump," Patel wrote. "With Encrypted Visibility Engine, you can now block this at the firewall."
