Why the Fundamentals You Ignored Are the Solely Issues That Will Save You
In 2023, a colleague and I wrote a cybersecurity information for companies of any dimension. It was not glamorous work. No one was asking for an additional whitepaper about multi-factor authentication (MFA) and community segmentation. The business had heard all of it earlier than: Harden your gadgets, section your networks, deploy endpoint detection and response (EDR), centralize your logs, take a look at your backups, validate your designs. These will not be revolutionary concepts. They’re the type of suggestions that get well mannered nods in shopper conferences after which get quietly dismissed someplace between funds approval and implementation.
We wrote the information anyway. Not as a result of I believed we had been saying one thing new, however as a result of after years of incident response work, I stored strolling into the identical rooms, wanting on the similar gaps, and having the identical conversations with organizations that had simply been breached. The assault vectors modified and the tooling developed, however the purpose organizations received harm was virtually at all times the identical – the fundamentals weren’t in place. In that paper we posed questions that, when answered truthfully on the strategic degree, might reveal the actual state of a corporation’s defenses. We coated endpoints, networks, cloud providers, bodily safety, staffing, and logging. It was designed to be helpful whether or not you had a group of 500 safety analysts or a single IT individual carrying a number of hats.
The core thesis was that patching alone will not be a safety technique. You want a basis that holds when patching fails – as a result of ultimately, patching will fail.
This state of affairs ultimately arrived in April 2026.
Anthropic introduced Challenge Glasswing and Claude Mythos Preview, an AI mannequin that autonomously found hundreds of high-severity zero-day vulnerabilities throughout each main working system and internet browser. Not theoretical weaknesses or potential points – working, exploitable vulnerabilities. One was undiscovered for 27 years in OpenBSD, the working system chosen particularly as a result of it’s stated to be among the many most safe on the planet. That is what occurs when vulnerability discovery stops being a human-speed exercise.
It dawned on me every part we wrote about in 2023 – each suggestion, each query we posed -had simply change into dramatically extra pressing, as velocity is the brand new issue within the conventional danger triad. Cisco set out the strategic model of this argument in its Shields Up steering after working with Mythos Preview. What follows is its operational companion.
The brand new math
Earlier than Mythos and different frontier giant language fashions (LLMs), the vulnerability lifecycle had a rhythm that almost all safety groups had internalized. A researcher discovers a vulnerability, and weeks or months move whereas an exploit will get developed. After a vendor releases a patch, organizations deploy it on their very own schedule. There was slack within the system, which gave organizations time to triage, take a look at, and be sluggish however nonetheless survive.
After AI and LLMs, the primary two phases of that lifecycle collapsed to near-simultaneity. AI discovers the vulnerability and writes the exploit in minutes, not weeks. However the final two phases, patch launch and patch deployment, stay human-driven processes working at human velocity. The hole between discovery/exploit and patch/deploy has widened from a manageable delay right into a structural hole.
The numbers make this concrete. The FIRST 2026 Vulnerability Forecast tasks a median of roughly 59,000 new CVEs this yr, with a 90% confidence interval reaching as much as 118,000. In 2025, 48,185 CVEs had been revealed, a 21% improve over the yr earlier than, which works out to roughly 131 new vulnerabilities disclosed each single day. NIST acknowledged that CVE submissions grew 263% between 2020 and 2025. Beginning April 2026, NIST introduced it could solely prioritize enrichment for CVEs showing in CISA’s Identified Exploited Vulnerabilities (KEV) catalog, software program utilized by the federal authorities, and significant software program below Government Order 14028. Every part else goes to the again of the road.
When speaking about this knowledge in buyer briefings, I framed it round three elements: the minutes from discovery to take advantage of, the hundreds of zero-days found, and the way AI accelerates attackers and defenders equally. The Cloud Safety Alliance was express about this of their April 2026 evaluation. The power to find vulnerabilities at AI scale will not be intrinsically a defensive functionality. It’s a dual-use functionality whose impact relies upon completely on who has entry and what constraints govern their use. We’re fortunate that frontier fashions take duty for the way they’re used, however there are various open-source fashions with much less oversight.
When vulnerability administration fails, who do you fall again on?
The way in which I take into consideration post-frontier mannequin protection, and the way in which I’ve been presenting it to safety leaders, follows a three-stage fallback mannequin.
The primary pillar is vulnerability administration. Scan, prioritize, patch, repeat. That is the place most organizations have concentrated their safety spending for 20 years. Patch velocity can not match AI-driven discovery charges. With 59,000+ CVEs projected for 2026 and rising, the quantity exceeds organizational capability to triage, take a look at, and deploy (in manufacturing, stay). Not all vulnerabilities even have patches on day zero; some are deemed as “operational danger,” or it could take years to revamp methods or {hardware}. Vulnerability administration will not be lifeless, however it’s now not the first line of protection; it’s now one enter amongst many. That is the place Cisco IQ turns into important. Its digital interface offers full asset visibility, safety hardening insights, and danger assessments, permitting you to proactively determine vulnerabilities and harden your methods within the face of mounting CVE volumes. Automating what you possibly can can be key to resilience acceleration.
When patching fails, you fall again to the second pillar: the “old fashioned” hardening that appears to be forgotten in period of EDRs. That is the place the 2023 whitepaper turns into a information:
We really helpful constructing golden photos that incorporate acceptable safety logging, refreshing them each 6 to 12 months, and making use of the newest hardening requirements. The whitepaper from 2023 asks questions that almost all organizations nonetheless can not reply confidently: Are well-known safety requirements for hardening adopted constantly throughout all gadgets? When was the final time core system golden photos had been reviewed for weaknesses? Are golden photos a part of safety critiques?
The third pillar is detection and response. Hardened methods don’t forestall exploitation, however make it tougher, slower, noisier, and survivable. Detection and response are what catches the exploitation that will get by, and in a post-AI exploitation world, some exploitation will get by. That is given and must be assumed.
This implies EDR, NDR, and XDR for visibility throughout layers. Behavioral detection is essential when zero-days outpace signature updates. An attacker utilizing an AI-discovered vulnerability nonetheless must execute code, set up persistence, transfer laterally, and exfiltrate knowledge. These actions produce behavioral alerts {that a} correctly configured EDR can detect no matter whether or not the precise vulnerability was beforehand recognized. It implies that we are able to use menace looking to seek out what automation misses. It additionally means you want incident response functionality for when prevention fails. New assaults will emerge. The query will not be whether or not you can be compromised. It’s now how shortly you possibly can detect, comprise, eradicate, and get better.
Validation will not be non-obligatory
Having the appropriate merchandise deployed is critical, however not ample. You additionally have to know the way they work – and right here is the place most organizations have a blind spot the dimensions of a continent.
The query each safety chief ought to be asking proper now’s “Do my controls truly work? Not on paper, however below real-world assault circumstances?” Penetration testing solutions that query. So does assessing your configurations in opposition to CIS benchmarks and hardening what falls quick. Risk modeling takes it additional by mapping the assault paths an actual adversary would use in opposition to your particular structure, not a generic danger matrix.
Breakout assessments deserve particular consideration. They take a look at the boundaries between community segments. Can an attacker transfer from a compromised endpoint to essential infrastructure? From IT to OT? From one enterprise unit to a different? In a post-AI world the place a zero-day can present preliminary entry to community section, the integrity of these boundaries is arguably a very powerful architectural property of your community. Discovering out they’re damaged earlier than an actual adversary does is the distinction between a containable incident and an existential disaster.
Then there’s the response aspect, and that is the place I see the widest hole between what organizations suppose they’ve and what they really have. IR playbooks which have by no means been examined will not be playbooks. They’re hopes. Purple group workouts are what flip these hopes into muscle reminiscence, the type that determines whether or not your group freezes or acts when an actual incident hits. Proactive menace hunts catch what your automation missed. When every part has been examined and nonetheless was not sufficient, emergency incident response is the potential that will get you from compromised to recovered.
The complete image is a cycle. You wish to forestall safety points with merchandise and hardening, validate with testing and evaluation, and reply with looking and incident response – all of it backed by menace intelligence, and all of it working collectively as a system, not as disconnected level options checked off a compliance spreadsheet.
What didn’t change
AI is not going to get uninterested in system exploitation, so danger will get realized a lot quicker than prior to now. Due to this, we now add “velocity” to danger equation. It turns into Danger = chance x influence x velocity versus simply Danger = chance x influence. AI doesn’t change the ideas of cybersecurity. MFA nonetheless blocks credential theft; segmentation nonetheless prevents exploit cascading into the setting; EDR nonetheless detects exploitation habits, reminiscence abuse, and makes an attempt to “write” to reminiscence segments; centralized logging nonetheless data occasions for detection and investigation; and examined backups nonetheless allow restoration.
These statements had been true earlier than any LLM/AI vulnerability discoveries, they’re true after LLM/AI, and they’re going to stay true after no matter comes after present stacks. As a result of they function at a layer of the safety stack that’s impartial of how briskly vulnerabilities are found. They work whether or not the attacker used a recognized CVE or a recent zero-day, and whether or not the exploit was written by a human researcher over three weeks or by an AI in three minutes.
That is the structural perception constructed across the whitepaper in 2023. No one had predicted that LLM/AI vulnerability discovery explosion, however we had seen, again and again in incident response engagements, that the organizations that survived breaches weren’t those with the quickest patching cycles. They had been those that had constructed their safety foundations earlier than the breach arrived. The present AI acceleration doesn’t watch for funds cycles, board approvals, or strategic plans. It rewards preparation and it punishes delays.
