Why Cisco is ringing the bell — and why you should listen
Cisco says aging routers, switches, and network-attached storage are a silent risk. Aging infrastructure. Silent risk. Those are not marketing words. They are a description of a gap between how these devices were built and how hostile the current threat environment has become. Many teams keep old devices running because it is cheaper and easier in the short term. I get that. Budget limits, operational disruption, and vendor complexity push people toward inertia. But that inertia has a price that rarely appears on the balance sheet: known vulnerabilities that attackers can find, and in some cases exploit without great skill.
What Cisco's "Resilient Infrastructure" actually does
Cisco has bundled research, outreach, and product changes under the name Resilient Infrastructure. The short list of actions: clearer end-of-life warnings, new prompts that call out insecure configurations at update time, and a road map to remove historic settings that are no longer safe. Those product moves will make it harder to keep old, insecure modes alive by accident. They will also force choices: either update configurations and software, or accept that some legacy interoperability will be removed.
How generative AI changes the threat equation
Generative AI does not yet roll out a multi-stage cyberattack without human help, but it already speeds the work attackers do. AI helps craft social-engineering lures, find likely weak spots, and automate parts of vulnerability reconnaissance. For low-skill attackers, that means a lower bar to start an attack. For well-funded teams, it means faster recon and faster refinement of tools. Put simply: aging infrastructure + more capable tooling for attackers = higher likelihood of a breach. Does that sound alarmist? Or does it sound like the arithmetic Cisco is laying out?
What the WPI Strategy study found — countries at different risk levels
Cisco commissioned WPI Strategy to look at end-of-life tech in five major economies: the United States, United Kingdom, Germany, France, and Japan. The study reported the United Kingdom, then the United States, face the largest relative exposure from outdated network tech in key sectors. Japan came out with the lowest relative exposure, credited to more consistent upgrade habits, decentralization patterns in infrastructure, and a stronger national focus on digital resilience. That pattern gives us a useful comparison: policy, procurement discipline, and system design make a measurable difference.
Board-level attention is not optional
Eric Wenger at Cisco put it plainly: the status quo is not free. There is a cost that organizations are ignoring because it lands in an operational bucket rather than on a board agenda. If the risk of aging infrastructure becomes a board-level issue, budgets and timelines change. If it does not, you keep paying in incident response and brand damage later. What will your board say when you ask for renewal money and explain the probability of a preventable breach?
Facing skepticism: is Cisco pushing upgrades to sell more gear?
Yes, Cisco sells networking gear. Call that out and move on. Cisco’s message still stands: whether you buy Cisco or another vendor’s product, you should replace unsupported, insecure devices. Anthony Grieco and Eric Wenger have said the conversation must start whether or not customers return to Cisco. That is the honest frame: this is about safety and resilience, not a vendor loyalty test. Will that argument convince procurement teams who are stretched thin? What would convince them?
Brains, not buzzwords: the technical changes that matter
Cisco’s plan to warn users about insecure settings when they update a device is practical. Removing deprecated options over time is technical hygiene. But concrete protection requires more than vendor prompts. Here’s what matters in the network:
1) Accurate inventory of devices and firmware versions. You cannot secure what you cannot see. 2) Risk-based classification: which devices sit in front of critical services, which can be isolated, and which are legacy access points. 3) Timely patching and replacement plans for devices at end-of-life. 4) Compensating controls for gear that cannot be replaced immediately: strict segmentation, proxying, and monitoring. 5) Updated procurement contracts that specify minimum support lifetimes, security patch commitments, and transparent disclosure at sale.
A practical roadmap for IT leaders
Start with the basics and work up to governance:
- Inventory and baseline: Do you have a single, trusted list of all network devices and their support status? If not, get one. - Prioritize by risk: Which devices would an attacker abuse to reach crown-jewel systems? Triage replacements accordingly. - Temporary controls: Apply network segmentation, access controls, and monitoring where you cannot replace hardware immediately. - Plan replacements: Budgets and schedules should be clear. If you cannot replace everything this quarter, pick the most exposed systems. - Board communication: Translate technical risk into business impact — likely cost of data loss, outage, and reputational harm. Tell the board what happens if you say "No" to upgrades; let them say "No" before an incident forces it. - Procurement and lifecycle policy: Require minimum support terms, security update commitments, and clear end-of-life notifications in contracts. Make vendors accountable for transition plans.
Operational tips for reducing exposure now
You can cut risk without a forklift upgrade. Use these actions today:
- Harden configurations: remove default credentials, close unused management ports, and enforce multi-factor access for admin interfaces. - Monitor for anomalous activity near legacy gear using network detection tools. - Apply virtual patches or filtering for known vulnerabilities where firmware patching is not possible immediately. - Harden supply chain checks: demand CVE disclosure and proof of patching practices from vendors. - Run red-team exercises that include legacy gear to see how an attacker might chain exploits.
Why this matters for public services and national resilience
The WPI Strategy results point to a broader truth: public services and utility providers often carry a heavier burden from aging tech. If a compromised device affects power distribution, transport control, or health services, the impact is more than an outage — it becomes a real public hazard. Japan’s lower relative exposure shows that policy choices and upgrade discipline can reduce this risk. What policy moves could your sector adopt to tighten upgrade cycles and procurement rules?
Leadership and persuasion: getting budget approved
This is where persuasion matters. Use social proof: show peers or sector examples who updated and avoided incidents. Use commitment and consistency: get an initial, small, measurable project approved and then expand. Use reciprocity: provide a short, independent risk brief to the board so they can act. Show authority with clear facts, not bluster. And acknowledge the pain: budgets are limited and replacing gear is disruptive. That empathy makes your pitch credible. What single metric would get your CFO to say yes?
Addressing the fears of CIOs and operators
Operators worry about downtime, integration headaches, and training. CIOs worry about budget optics and procurement cycles. Those worries are real. They are also solvable. Plan phased replacements with parallel testing, vendor-assisted migrations, and rollback plans. Use pilot projects to prove the approach. Keep the conversation honest: you will not replace everything overnight, but you can reduce the highest risk first. Will your operations team accept a staged approach?
What boards should ask their IT leaders next week
Boards should ask direct, actionable questions. Here are three to use now:
- What percentage of our network infrastructure is at or past vendor support? - If an attacker exploited a legacy device this month, what services would be affected and what would be the business impact? - What is the timeline and budget needed to reduce our highest-risk legacy exposures to an acceptable level?
Luck favors the prepared, not the hopeful
Cisco is trying to make the silent risk loud. That will force choices. Some companies will upgrade. Others will accept the risk. Both options are legitimate, but the choice matters. Say no to pretending the status quo is free. Say yes to a clear, measurable plan to reduce exposure. What will you choose?
