Lean teams, outsized coverage
How security teams of five carry the workload of fifty with Cantina: closing every loop from first discovery to verified fix, across smart contracts, bridges, and live infrastructure.
How lean teams scale
How a five-person team runs like fifty
Cantina's agents carry the repetitive weight, triaging signals, reproducing issues, drafting fixes, and re-verifying they land, so a small in-house team spends its hours on judgment, not toil. The coverage scales; the headcount doesn't.
Every loop closed on record. Logged, attributable, and re-verified after each fix ships.
A typical engagement
- In-house team
- 5
- Effective coverage
- 50+
- Loops closed on record
- 100%
Outcomes
What lean teams ship with Cantina
Across every engagement, the pattern repeats: a small in-house team closes far more of the loop, faster, without adding headcount.
- Coverage per security engineer vs. a traditional audit cycle
- 0× Coverage per security engineer vs. a traditional audit cycle
- Assets under continuous review across active engagements
- $0B+ Assets under continuous review across active engagements
- Programs run by teams of five or fewer
- 0+ Programs run by teams of five or fewer
- Median time from first finding to a verified fix
- 0h Median time from first finding to a verified fix
“We run a five-person security function. Cantina lets us behave like a team ten times that size, every finding gets triaged, investigated, and closed on the record, without us adding a single hire.”
