Building the future
@ everyone who works at a company looking for answers to "what should we do about security", here's an excellent answer. I'd say this is the 80/20. Most people trying to secure their systems don't understand the threat model -- who and what are you defending against? Most exploit chains in practice are just variations of phishing/supply chain attack and use local employee devices as the break-in
1. Mercor has insane revenue growth 2. Mercor is a heavy user of Devin This is not a coincidence! We're seeing more and more amazing tech companies adopt Devin for all their work and seeing huge efficiency gains as a result.
We've been sprinting to launch this new improved Devin Security -- now powered by frontier cyber models. We're offering free scans to eligible enterprises starting TODAY, because when it comes to security, every second counts.
