What their customers say

Quotes from people at RunSybil's customers.

““RunSybil’s expertise was instrumental in enhancing our security posture, providing us with critical insights for a confident launch.””

Philip Howes · CTO · Baseten

“"RunSybil was an excellent partner for us. They pressure-tested our systems ahead of a major release and delivered fast, high-quality results at a competitive price on par with top pen-testing firms."”

Dana Bost · Senior Technical Program Manager · Notion

““We wanted a world-class partner for Turbopuffer’s ongoing pentesting needs, and we couldn’t be happier with our relationship with RunSybil. Quick turnaround, attention to detail, and fun to work with—a partner that will grow with us ❤️🔥””

Simon Eskildsen · CEO · Turbopuffer

“The bug bounty has lost its charm. They're using the same tools to scan us externally as we're using internally. But it's more than that: they're finding the same patterns on repeat, farming bounties instead of the novel vulns, like XSS-to-RCE chains, that used to make this worth it.”

Vamsi NC · AppSec Lead · Carta

“The real shift left is in findings becoming detection patterns powering the appsec flywheel where we push less vulnerabilities and we build confidence as there is continuous and deeper coverage of our attack surface”

Brad Freer · Senior Security Engineer · Carta

““When it comes to cybersecurity, we have to go faster because the attackers are going faster,” Moles explains. “Continuous automated testing is directionally where business needs to go. Anything I can do to stay on top of cybersecurity, identifying and detecting things faster behooves me as a technology leader to do.””

Joseph Moles · CTO and CISO · Furl.ai

““We take the trust our customers put in us to protect them, their data, and their systems very seriously,” says Abdine. “We’re shipping new releases every one to three days, so we’re pretty fast. That kind of speed requires an extra level of diligence so we can maintain customer confidence.””

Derek Abdine · CEO and co-founder · Furl

““When customers are taking a bet on a young company, there isn’t a lot of forgiveness,” he explains. “When there’s a greater level of trust involved, you don’t want to take that for granted.””

Derek Abdine · CEO and co-founder · Furl

““As a one-man-band here, this gives me one less critical thing to worry about,” he adds. “Especially as a security company, it’s important to have active testing with an agent so we have layers of controls and checks.””

Joseph Moles · CTO and CISO · Furl.ai

““Whenever we can plug any holes we are safer,” says Moles. “And a big value to me is that someone didn’t just hand me more than 500 findings that I needed to go through to find the few important ones. That would have been death by a thousand cuts. Having that distilled down to two or three issues that needed to be addressed took away what would have been a problem. This test gave me a higher level of confidence and one less thing to worry about.””

Joseph Moles · CTO and CISO · Furl.ai

““That was just stupid fast,” he says. “We have to find issues and fix them quickly to keep up. Anything I can do to identify and address vulnerabilities faster behooves me. And that’s what we did here. I was impressed by the quick turnaround.””

Joseph Moles · CTO and CISO · Furl.ai

““It was a set-it-and-forget-it kind of situation because I just hit a button and could let it run on its own,” says Moles. “I didn’t have to manage people. I didn’t have to manage the operation. It was great because it was so hands-off.””

Joseph Moles · CTO and CISO · Furl.ai

““In terms of a fast turnaround, ease of use, and a low overhead, RunSybil gave me what I needed so we could meet those requirements,” he adds. “It helped us get that customer.””
