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 measurement. It was not glamorous work. No person was asking for one more whitepaper about multi-factor authentication (MFA) and community segmentation. The trade had heard all of it earlier than: Harden your units, section your networks, deploy endpoint detection and response (EDR), centralize your logs, check your backups, validate your designs. These are usually not revolutionary concepts. They’re the type of suggestions that get well mannered nods in shopper conferences after which get quietly dismissed someplace between price range 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 identical gaps, and having the identical conversations with organizations that had simply been breached. The assault vectors modified and the tooling developed, however the cause organizations obtained harm was virtually all the time the identical – the fundamentals weren’t in place. In that paper we posed questions that, when answered actually on the strategic degree, may reveal the true state of a corporation’s defenses. We lined 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 particular person sporting a number of hats.
The core thesis was that patching alone shouldn’t be a safety technique. You want a basis that holds when patching fails – as a result of finally, patching will fail.
This state of affairs finally arrived in April 2026.
Anthropic introduced Undertaking Glasswing and Claude Mythos Preview, an AI mannequin that autonomously found hundreds of high-severity zero-day vulnerabilities throughout each main working system and net 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 mentioned to be among the many most safe on the earth. That is what occurs when vulnerability discovery stops being a human-speed exercise.
It dawned on me every little thing we wrote about in 2023 – each suggestion, each query we posed -had simply grow to be 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 steerage after working with Mythos Preview. What follows is its operational companion.
The brand new math
Earlier than Mythos and different frontier massive 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, check, 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 initiatives 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% enhance 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 demanding software program underneath Government Order 14028. The whole lot else goes to the again of the road.
When speaking about this information in buyer briefings, I framed it round three components: the minutes from discovery to use, the hundreds of zero-days found, and the way AI accelerates attackers and defenders equally. The Cloud Safety Alliance was specific about this of their April 2026 evaluation. The flexibility to find vulnerabilities at AI scale shouldn’t be intrinsically a defensive functionality. It’s a dual-use functionality whose impact relies upon totally 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 numerous open-source fashions with much less oversight.
When vulnerability administration fails, who do you fall again on?
The best way 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 twenty 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, check, and deploy (in manufacturing, dwell). Not all vulnerabilities even have patches on day zero; some are deemed as “operational danger,” or it could take years to revamp techniques or {hardware}. Vulnerability administration shouldn’t be useless, 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 supplies full asset visibility, safety hardening insights, and danger assessments, permitting you to proactively determine vulnerabilities and harden your techniques 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 skool” hardening that appears to be forgotten in period of EDRs. That is the place the 2023 whitepaper turns into a information:
We really useful constructing golden photographs that incorporate acceptable safety logging, refreshing them each 6 to 12 months, and making use of the most recent 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 persistently throughout all units? When was the final time core system golden photographs had been reviewed for weaknesses? Are golden photographs a part of safety evaluations?
The third pillar is detection and response. Hardened techniques don’t stop exploitation, however make it more durable, slower, noisier, and survivable. Detection and response are what catches the exploitation that will get by means of, and in a post-AI exploitation world, some exploitation will get by means of. 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 information. These actions produce behavioral alerts {that a} correctly configured EDR can detect no matter whether or not the particular vulnerability was beforehand identified. It implies that we will use menace looking to search out what automation misses. It additionally means you want incident response functionality for when prevention fails. New assaults will emerge. The query shouldn’t be whether or not you can be compromised. It’s now how rapidly you possibly can detect, comprise, eradicate, and recuperate.
Validation shouldn’t be optionally available
Having the appropriate merchandise deployed is important, 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 needs to be asking proper now could be “Do my controls truly work? Not on paper, however underneath real-world assault circumstances?” Penetration testing solutions that query. So does assessing your configurations towards CIS benchmarks and hardening what falls brief. Risk modeling takes it additional by mapping the assault paths an actual adversary would use towards your particular structure, not a generic danger matrix.
Breakout assessments deserve particular consideration. They check 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 an important 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 facet, and that is the place I see the widest hole between what organizations assume they’ve and what they really have. IR playbooks which have by no means been examined are usually not playbooks. They’re hopes. Purple group workout routines 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 little thing has been examined and nonetheless was not sufficient, emergency incident response is the aptitude that will get you from compromised to recovered.
The complete image is a cycle. You wish to stop 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 won’t get uninterested in system exploitation, so danger will get realized a lot quicker than previously. Due to this, we now add “velocity” to danger equation. It turns into Threat = chance x affect x velocity versus simply Threat = chance x affect. AI doesn’t change the rules of cybersecurity. MFA nonetheless blocks credential theft; segmentation nonetheless prevents exploit cascading into the atmosphere; 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 unbiased of how briskly vulnerabilities are found. They work whether or not the attacker used a identified CVE or a contemporary 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 person had predicted that LLM/AI vulnerability discovery explosion, however we had seen, time 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 look forward to price range cycles, board approvals, or strategic plans. It rewards preparation and it punishes delays.
