Verdict

Synack earns its rank with a unique model that combines a crowdsourced team of elite, vetted researchers with an AI-enabled platform for continuous testing.

What customers praise

The Synack Red Team (SRT) is heavily vetted, with a reported acceptance rate under 10%, ensuring a high signal-to-noise ratio compared to public bug bounty programs.

The model is premium-priced and better suited for ongoing programs than for one-off compliance pentests, which can make it a budget challenge for smaller companies.
