A Reliable Security Partner with Great Customer Support

Great customer service, with clear communication around the cost, scope of work, and timeline. Their expertise is exceptional. They asked clarifying questions whenever necessary and helped us identify real security issues quickly with actionable guidance so that we could remediate them before the deadline. The final report was well organised and thoroughly documented.

Exceptional Security Partner for High-Stakes Blockchain Projects

We build and ship blockchain products for demanding clients, and CyStack is the team we call when failure is not an option. A good example is 1Ma**** – a network made by Vietnamese for Vietnamese, backed by leading financial and tech groups and tied to the country’s national blockchain strategy. On projects like that, what I appreciate most is that CyStack doesn’t give us a pretty PDF and disappear. They pressure-test the design, find real issues (not theoretical noise), sit down with our engineers, and stay with us through remediation and re-testing. We’ve done multiple audits with them now, and the pattern is consistent: clear priorities, practical fixes, and no drama.
