Defend against frontier AI threats at runtime | F5

Frontier AI is collapsing the patch window from weeks to minutes. Protect against threats with software that’s continuously hardened using the latest frontier AI models, while leveraging solutions that enforce protection in the data path before threats reach your apps, APIs, and AI models.
Frontier AI enables previously undiscovered attacks, which evade traditional defenses that depend on signatures to known vulnerabilities.
Threat actors can now exploit vulnerabilities within hours of discovery. Security teams are used to longer patch cycles, exposing critical gaps in protection.
Every patch release reveals vulnerabilities that attackers can reverse-engineer quickly, turning unpatched systems into easy targets before organizations can deploy updates.
To combat frontier AI threats, organizations need comprehensive solutions that provide runtime protection, virtual patching, and AI-driven threat mitigation to block attacks and adapt to evolving risks.
F5 harnesses the latest frontier AI models to continuously harden our code across the F5 Application Delivery and Security Platform, systematically finding and fixing vulnerabilities at machine speed.
F5 ships critical software releases every six weeks with fixes from our 5-step model-agnostic AI scanning harness infrastructure, internal teams, and outside researchers.
F5 uses a 5-step AI scanning harness loop and the most advanced frontier AI models to help identify potential weaknesses earlier and validate improvements faster, hardening the products customers rely on to protect their most critical applications.
Using the most advanced frontier AI models, F5 runs a continuous scanning harness that finds, validates, and fixes vulnerabilities, hardening the products customers rely on. The approach is model-agnostic by design, so protection is never bound to a single vendor.
F5 shifts protection to the runtime layer, blocking threats instantly before they can reach your applications or APIs. With solutions like AI-powered WAF, virtual patching, and real-time threat mitigation, F5 stops zero-days, AI-driven exploit chains, and unauthorized access while ensuring legitimate traffic is uninterrupted.
This AI-powered WAF improved baseline threat detection to 98% accuracy while reducing false positives to 1%.
Automated vulnerability detection and virtual patching uncovers vulnerabilities with assigned CVE scores and severity levels to BIG-IP Advanced WAF, with automatic policy updates.
Detects and identifies AI agents, humans, and bots by assigning a trust score that governs their actions. This score controls what they can do, where they can operate, and how quickly they can act, blocking automated abuse.
Continuously discovers APIs, including shadow and unmanaged endpoints, monitors for abuse and sensitive data exposure, controlling and protecting endpoints inline to stop threats before they reach your services.
Inspects prompts and responses at the inference layer in real time, blocking prompt injection, data leakage, and unsafe output.
Continuously probes your models and AI applications for exploitable weaknesses, surfacing them the way an attacker would before one does.
Converged WAF, API security, bot defense, and DDoS mitigation that enforce one consistent policy across every environment, closing the gaps that tool sprawl leaves open.
End-to-end protection for AI models, applications, and agents, from red teaming in development to runtime guardrails in production, across hybrid multicloud environments.

F5 collaborates with leading organizations across the AI, security, and open-source communities to help strengthen cyber resilience and advance collective defense in the Frontier AI era.
Frontier AI has fundamentally changed the vulnerability lifecycle. Models can now discover vulnerabilities at machine speed, and exploits increasingly appear before your security teams can patch them. Join F5 and industry leaders to discover best practices for securing apps, APIs, and models in the post-Mythos world.
Frontier AI refers to the most advanced AI models available at a given time. In cybersecurity, it is used on both sides of the threat. Many models available broadly today are already very good at reverse engineering, web application penetration testing, red teaming, and vulnerability research. This is compressing the time between vulnerability discovery and exploitation, which collapses the patch window and leaves traditional patch cycles exposed. Models like Mythos and GPT-5.5-Cyber offer longer context windows, reduce safeguards that can limit security research, and can effectively use external tools to help attackers chain complex exploits
