Modern Web Security

Defending every site, against the next era of attacks.

A.AI secures websites, applications, and APIs against everything from credential stuffing and SQL injection to supply-chain compromise and AI-driven exploitation. We bring frontier capabilities — including Mythos-class models — to every layer of your defense.

The new threat surface

Your site is being attacked by capabilities that didn’t exist a year ago.

The classics haven’t gone away — credential stuffing, injection, business-logic abuse, dependency compromise. They’ve just been joined by AI-augmented attackers who can write working exploits in hours, against software that survived decades of human review.

27y

The OpenBSD bug nobody saw

A frontier model found a TCP SACK vulnerability in OpenBSD — one of the most security-hardened operating systems in existence — that had survived since 1998. It allowed any attacker to remotely crash any machine running it.

5M

Fuzzer hits, missed every time

A 16-year-old vulnerability in FFmpeg’s H.264 decoder — code that automated tools had hit five million times without catching the issue — was found autonomously by a frontier model.

root

Unauthenticated, over the internet

CVE-2026-4747: a 17-year-old remote code execution in the FreeBSD NFS server. A frontier model wrote a multi-packet ROP exploit that gives any unauthenticated attacker full root.

1

One click → kernel write

Frontier models have chained four vulnerabilities into a JIT heap-spray that escapes the browser sandbox and writes directly to the OS kernel. Triggered by visiting a webpage.

2 → 181

Exploit speed, collapsed

On a Firefox 147 benchmark, the prior-generation model produced 2 working exploits across hundreds of attempts. A single new frontier model produced 181 — in one release.

$0

Expertise, approaching free

Engineers with no formal security training have asked frontier models to find remote code execution bugs overnight, and woken up to a working exploit. The cost of attack expertise is approaching zero.

The model

Mythos-class defense, at the speed of attack.

Mythos is a frontier security model that has identified thousands of high- and critical-severity vulnerabilities across every major operating system, every major web browser, and the world’s most relied-on cryptography libraries. Anthropic does not make Mythos generally available — access runs through Project Glasswing and a small set of vetted defenders. A.AI plugs Mythos-class capabilities into your perimeter, so your site benefits from the same analysis that found a 27-year-old OpenBSD bug in a single afternoon.

The consortium

The organizations already deploying Mythos.

Anthropic launched Project Glasswing with twelve founding partners using Mythos Preview to secure the world’s most critical software. The defensive work happening behind these names is the same class of capability A.AI brings to your perimeter.

What we cover

Full-spectrum security for everything you ship to the public internet.

Whether you run a marketing site, a SaaS app, an e-commerce platform, or an AI product, the perimeter is the same — and it needs the same end-to-end coverage. We do the unglamorous core work as well as the frontier-only stuff.

01

Perimeter & edge defense

WAF, DDoS mitigation, rate limiting, TLS hardening, CDN configuration, and origin shielding. The essentials, done properly — with intent-aware rules instead of brittle signatures.

02

Application security

Continuous code review, dependency & supply-chain scanning, secrets detection, SAST/DAST orchestration, and manual review of high-risk surfaces — auth, sessions, payments, file upload.

03

Identity & access

MFA rollout, SSO integration, session hygiene, account takeover defense, credential-stuffing protection, and bot versus human classification at the login boundary.

04

Monitoring & incident response

24/7 detection across application, infra, and identity logs. Triaged alerts written for engineers. Forensic capability and regulatory-grade reporting when something does go wrong.

05

Penetration testing & red teaming

Pre-launch assessments, scheduled annual pentests, and continuous Mythos-class red teaming for clients who can’t afford to wait between engagements. Reports come with proof-of-exploit, not noise.

06

AI & agent security

For sites that ship AI features: prompt-injection defense, jailbreak detection, agent traffic control, and data-boundary enforcement on every model endpoint. Optional, not assumed.

Receipts

Real bugs. Real exploits. Already in the wild.

These vulnerabilities were identified, and in many cases exploited, fully autonomously by frontier models. Each existed in production for years. We watch this surface so your business doesn’t end up on a future version of this list.

OpenBSD · TCP SACK27 years undetected

Remotely crash any machine running OpenBSD.

A subtle integer overflow in the SACK linked-list walk let attackers send a single crafted TCP segment that dereferenced a NULL pointer in the kernel. OpenBSD runs many of the world’s firewalls and routers.

FreeBSD NFS · CVE-2026-474717 years undetected

Unauthenticated root from anywhere on the internet.

Stack buffer overflow in RPCSEC_GSS, fully exploited autonomously — including a multi-packet ROP chain that appended the attacker’s SSH key to authorized_keys. Generated from a single prompt.

FFmpeg · H.264 codec16 years undetected

Out-of-bounds heap write from a single video frame.

A 2003 design choice combined with a 2010 refactor created a vulnerability that no fuzzer — even campaigns hitting it five million times — ever surfaced. FFmpeg powers nearly every video pipeline online.

Linux kernelLocal privilege escalation

From unprivileged user to full root, autonomously.

Frontier models chained two, three, sometimes four kernel vulnerabilities — bypassing KASLR, leaking pointers, spraying the heap, overwriting page-table entries — to hand any local user complete control.

Every major web browserJIT spray + sandbox escape

One webpage. A direct write to your kernel.

Models autonomously discovered the read and write primitives, chained them through the JIT, escaped the renderer sandbox, and landed in the OS kernel. Many of these exploits remain unpatched.

Cryptography librariesTLS · AES-GCM · SSH

Forge certificates. Decrypt traffic. Bypass auth.

Frontier models surfaced critical issues in the libraries underpinning the modern internet — including a certificate-authentication bypass disclosed in 2026. The libs you trust are now also the ones AI is auditing.

Our approach

Security that thinks at the same speed as the attack.

Traditional WAFs see traffic. Signature engines see strings. A.AI sees intent — combining frontier reasoning, hardened edge infrastructure, and continuous red-team telemetry to stop attacks no rule set can describe.
