CyStack Security Services Reviews & Provider Details

I really appreciate CyStack Security Services for their strong capability in securing and monitoring our cloud infrastructure and web applications, which has been crucial for us over the past year. Their vulnerability scanning, website protection, and secrets management features are top-notch. Switching from another provider turned out great because CyStack offered more localized support, faster response times, and better integration with our existing infrastructure, which made our transition smooth and cost-effective. They took the time to understand our infrastructure and security workflow in detail, which truly sets them apart. CyStack has been instrumental in addressing major challenges like vulnerability management, data protection, secrets management, and continuous monitoring. Their seamless integration with our Kubernetes cluster and cloud systems is impressive—it operates efficiently without degrading performance, and it generates quick, actionable reports. It's a lightweight and developer-friendly solution that heightened our security with minimal effort. I highly value their expertise and proactive approach; their vulnerability assessments are detailed, and the team's practical recommendations are clear and useful rather than just raw data. The combination of automated scanning with manual verification ensures high accuracy with fewer false positives. I also appreciate CyStack's reliability, responsiveness, and deep technical expertise. Their team consistently provides high-quality insights, quick support, and solutions adaptable to our growing infrastructure. The sense of reliability and continuous monitoring without interruptions gives us great confidence. Review collected by and hosted on G2.com.

I have been using CyStack Security Services for over three years and have found their work extremely valuable. I am particularly impressed by their thoroughness in conducting security audits for our blockchain project, which helped identify and fix potential vulnerabilities in our smart contracts and system infrastructure. This, in turn, strengthened our project's security and built greater trust with our users and partners. I greatly value CyStack’s professionalism and attention to detail. Their audit reports are clear and easy to understand, with transparent steps for addressing issues. Additionally, the responsiveness of their team and their technical expertise make the entire engagement process smooth and reliable. CyStack's strong reputation and experience in the blockchain arena initially drew us to them, and their commitment to quality and consistent support has been reassuring. I appreciate their transparency and find their reliable support and commitment to quality as factors that make me confident in our ongoing partnership. My experience with CyStack has been so positive that I would unreservedly recommend them, rating my likelihood of recommending them a 10 out of 10. Review collected by and hosted on G2.com.

I've had a great experience with CyStack. One thing I'd love to see in the feature is more ongoing security monitoring or periodic re-audits to ensure long-term protection. Review collected by and hosted on G2.com.

CyStack's technical team is excellent. They don't just run standard tests - they really think like attackers. They understand how modern applications are built and how to exploit business logic flaws, not just basic vulnerabilities. What impressed me most is their professionalism and consistency - every engagement was well-documented, and their findings were always reproducible and clearly explained.

Honestly, there's not much to dislike. If I had to mention something, maybe their schedule can get busy during high-demand periods - which just shows how many companies trust them. But they always communicate clearly and deliver as promised. Review collected by and hosted on G2.com.

Whether it's regular vulnerability scanning reports or immediate support during urgent security incidents, the CyStack team handles issues in a systematic, clear, and professional manner.

Their security testing results not only identify risks but also provide actionable remediation suggestions, making the entire improvement process highly efficient. Review collected by and hosted on G2.com.

CyStack's technology and reporting quality are both excellent, but the format and visual presentation of its reports can sometimes be a bit technically oriented.

For non-technical departments (such as management or clients), the presentation could be further optimized to make it easier to understand and make decisions.

In addition, we would like to see some communication processes (such as progress tracking and status updates) become more automated and timely. Review collected by and hosted on G2.com.

CyStack helped us build a full security program without slowing down our product growth. Their team combines continuous monitoring, manual pentests, and a bug bounty program, which gave us visibility on risks across our apps, cloud, and backend. Critical issues like SQL injection or data leaks were detected and fixed within 1–2 days instead of weeks. Review collected by and hosted on G2.com.

There isn’t much to dislike. That said, they were always transparent about timelines and kept us updated throughout the process. Review collected by and hosted on G2.com.

They act like a partner. Senior testers who speak both engineering and boardroom. Findings ranked by real risk, “here’s how we got in” and “here’s how you close it,” followed by quick retests. The red team documentation laid out the kill chain in plain language. Leadership engagement when needed - no runaround. Review collected by and hosted on G2.com.

Minor thing: the first report was a bit dense for an exec read. We asked for a tighter summary and they adjusted the next cycle - problem solved. Review collected by and hosted on G2.com.
