Security testing that
actually works.
Deploy autonomous AI agents that test your employees with nation-state level sophistication — before the real attackers do.
How it works
So simple, bad actors wish they could use us.
From first login to a fully autonomous campaign in under 5 minutes. Keep scrolling.
AI plans every test like a real adversary
Give the agent a mission objective and it builds the full kill chain — reconnaissance, persona and pretext construction, initial contact, trust building, and the exploitation ask. Every step is laid out with success criteria before anything runs.
Vyvern gives security teams a safe, controlled way to run real social-engineering attacks. Our agents operate on the same channels your employees use every day.
Vyvern tests every channel attackers actually use
Spear-phishing emails written in your company’s own voice — referencing real projects, real vendors, and real colleagues.
Social Media
Recruiter pitches and DMs built from each employee’s public footprint — their talks, repos, and connections.
IT Helpdesk
Your VPN certificate expires today. Re-verify your credentials to keep access…
SMS
Smishing campaigns that mirror the texts your tools and vendors actually send — MFA prompts, delivery alerts, IT notices.
Voice
AI vishing calls that test phone-based verification under pressure — the fastest-growing attack vector in the wild.
