USENIX Security '27 — 36th USENIX Security Symposium

USENIX Security '27, the 36th USENIX Security Symposium, runs 11-13 August 2027 at the Hyatt Regency Denver at Colorado Convention Center in Denver, Colorado. USENIX Security is one of the four conferences the security research community treats as top-tier, and its declared topic areas now include machine learning security and privacy alongside system security, network security, web, mobile and emerging technology security, software security, privacy and anonymity, human aspects of security, security measurement studies, hardware security and cryptographic applications. The symposium runs two full review cycles a year, each with mandatory paper registration a week before submission, an early-reject stage, a week-long author rebuttal and a final-papers deadline — a process that is why USENIX papers tend to arrive with working artifacts rather than claims. Cycle 1 closes in August 2026 and Cycle 2 in January 2027.

• ✓CISOs and heads of security engineering
• ✓AI security and model red-team leads
• ✓Application and product security engineers
• ✓Privacy engineers and data protection leads
• ✓Threat researchers and detection engineers
• ✓Security academics and PhD students

This is where the AI-specific attack surface — model extraction, training-data poisoning, prompt-mediated privilege escalation, agent tool abuse — gets its first peer-reviewed treatment, months before it reaches a vendor datasheet. A CISO gets three days of results produced by people with nothing to sell, plus open-access papers and artifacts the team can reproduce internally against your own stack. Scheduling it in Denver in August makes it a practical add-on to the Las Vegas security week, and USENIX's rebuttal-heavy review means far less time wasted on findings that will not replicate.

• ✓Main symposium track across ten declared topic areas including ML security and privacy
• ✓Two-cycle peer review with mandatory paper registration and submission artifacts
• ✓Early reject notification stage in each cycle
• ✓Week-long author rebuttal period in each cycle
• ✓Open-access proceedings published by USENIX
• ✓Co-located workshops and events announced with the programme

• ★Machine learning security and privacy is a standing declared topic area, so attacks on models, training data and AI pipelines are in the main programme rather than a co-located workshop
• ★Two full review cycles a year with mandatory pre-registration of papers, an early-reject stage and a week-long rebuttal — an unusually heavy process that filters weak results before they reach the stage
• ★Run by the USENIX Association, a non-profit with a long-standing open-access policy: papers and often artifacts are freely available rather than paywalled
• ★Denver in August, immediately after Black Hat and DEF CON week, making a combined US security trip practical
• ★One of the four venues the research community treats as top-tier, and the one most consistently oriented toward systems work with running code

USENIX normally posts member, non-member and student tiers with an early-bird cutoff roughly two months before the symposium; proceedings themselves are open access and free.
