# Synack Reviews **Vendor:** Synack **Category:** [Penetration Testing Tools](https://www.g2.com/categories/penetration-testing-tools) **Average Rating:** 4.8/5.0 **Total Reviews:** 16 ## About Synack Synack is a continuous penetration testing platform that combines agentic AI with a global network of vetted security researchers to uncover real, exploitable vulnerabilities across the entire attack surface. Most organizations test only a fraction of what matters. Synack closes that coverage gap—using AI to scale discovery and human expertise to validate real risk. The platform enables enterprises to move from periodic testing to continuous security validation across web applications, APIs, cloud, and infrastructure—prioritizing findings based on what is actually exploitable, not just detected. Synack supports penetration testing, continuous security testing, vulnerability management, and attack surface management in dynamic, cloud-based, and hybrid environments. Founded by former NSA professionals, Synack supports enterprise and public sector organizations where security, compliance, and risk management are mission-critical. ## Synack Reviews ### 1. Trusted Long-Term Partner with Responsive Support and Continuous Innovation **Rating:** 5.0/5.0 stars **Reviewed by:** Khai D. | Manager - Cyber Defense, Enterprise (> 1000 emp.) **Reviewed Date:** April 08, 2026 **What do you like best about Synack?** We’ve been using Synack for a number of years and consider them a trusted, long-term partner. Their flexibility and willingness to work with our evolving needs has been a major differentiator, and their support teams have been consistently responsive and reliable—especially over the past few years as our environment and requirements have continued to grow. From a security perspective, we strongly value Synack’s crowdsourced testing model. Having a diverse pool of vetted researchers means our applications are continuously tested by individuals with varying skill sets and areas of expertise, which provides broader and more realistic coverage than traditional approaches alone. The Synack platform itself has evolved significantly during our time as a customer. It’s clear they are not standing still—the platform is regularly updated with new features and capabilities, more recently around analytics and scope coverage, which has improved both visibility and executive-level communication. We also appreciate that Synack is actively investing in and leveraging AI within their ecosystem rather than simply coasting on past success. Synack has proven to be a strong partner that continues to innovate while maintaining the operational maturity and support we rely on. **What do you dislike about Synack?** In the past, I had some concerns around the depth of analytics and the data available across different assessments. At the time, it was difficult to easily dive into detailed metrics and trends at the level we wanted. Synack has since addressed this gap by rolling out much more robust analytics, and overall data visibility, which has significantly improved the experience. I will note that Reporting has always been good.   Another past challenge was ensuring consistent “eyes on” coverage from researchers across our assessments (having the same assessment running year over year can be a challenge). Synack listened to feedback and has taken tangible steps to improve this over time. That said, this is also a shared responsibility—customers need to keep scopes current, ensure red team context is updated, and periodically review and tune assessments to get the best results. **What problems is Synack solving and how is that benefiting you?** Our business needs a penetration testing partner that is flexible and able to quickly spin up or adjust assessments as priorities shift. Synack solves that by providing an on-demand, scalable testing model that consistently supports our changing schedules year over year. In addition, Synack addresses the challenge of managing and coordinating ongoing testing through a highly engaged customer success team. Their team actively works with us, understands our environment and requests, and moves quickly to support changes in scope or approach—resulting in smoother assessments, faster execution, and a more reliable testing program overall. **Official Response from Angela Heindl-Schober:** > Khai, thank you — this really means a lot, especially given the journey we’ve been on together. It’s great to see the impact of continuous testing and the depth that comes from combining our researcher community with the platform. And I appreciate you calling out the evolution on analytics and coverage, that’s where we’re investing. Let’s build on this. I’d love to explore how we can further expand coverage and give your team even more visibility across your attack surface. Happy to connect anytime. Angela ### 2. Powerful Security with Flexible Licensing **Rating:** 4.5/5.0 stars **Reviewed by:** Todd E. | Small-Business (50 or fewer emp.) **Reviewed Date:** April 06, 2026 **What do you like best about Synack?** I appreciate that Synack explains exactly how each flaw was exploited and provides a full detailed explanation on how to remediate the flaw. This reduces developer toil by cutting down the time needed to develop the remediation, and it's like getting secure code training for free. Customers purchase credits, not tests, allowing for the credits to be used for any type of test offered, even to customize tests, making the licensing model extremely flexible. Synack is more important than just checking a compliance box; it does more than merely validating controls are in place. It validates if those controls work, and it can confirm that remediations have actually fixed problems. Unlike standard compliance checks like SAST scans, it doesn't just test against known requirements but also looks for unknown failures like logic flaws, insecure workflows, auth bypasses, etc. **What do you dislike about Synack?** Sometimes they have been a little slow to spin up their red teams, but all it takes is a follow up call and they are always willing to up the priority. The setup is easy for the most part, but can get a little more complicated when API and/or multiple testing accounts are involved. **What problems is Synack solving and how is that benefiting you?** Synack helps us prioritize remediation by finding exploitable flaws, reducing developer toil with detailed explanations, and acting as secure code training. It's flexible with credits for tests and validates both known and unknown control effectiveness, unlike traditional compliance checks. **Official Response from Angela Heindl-Schober:** > Todd, thank you, this is a fantastic review and we really appreciate the depth you went into. Your point on validating real control effectiveness (not just checking compliance) gets to the heart of what we’re building. If we’re not finding what actually breaks in the real world—and helping teams fix it—we’re not doing our job. Great to hear the detailed findings and remediation guidance are reducing developer toil. That’s exactly the outcome we want: not just identifying issues, but making them actionable and useful for engineering teams. Also appreciate the candid feedback on red team spin-up and API complexity—we’re actively working on improving both, especially as environments become more distributed and API-heavy. Thanks again for your partnership and for taking the time to share this. Angela ### 3. Unique Approach but Needs Market Adaptation **Rating:** 4.0/5.0 stars **Reviewed by:** Jason L. | Enterprise (> 1000 emp.) **Reviewed Date:** April 11, 2026 **What do you like best about Synack?** I like the unique way in which Synack operates. They pull from a differentiated set of attackers or thought leaders, which feels innovative. The way they represent and present the information back to me on what they found is something that I appreciate. **What do you dislike about Synack?** I'm a bit concerned about the cost pressures with Synack, in terms of always needing to do more with less. I feel that Synack needs to rethink its approach to the market because the buying cycle and the economic buyer have shifted. I also think there's a need to focus more on how the service ties into enterprise resiliency rather than just standard break-fix penetration testing. The space has become more commoditized, which makes conversations about it more difficult and a tougher fight to keep it relevant. **What problems is Synack solving and how is that benefiting you?** Synack highlights where we have vulnerable systems exposed to attackers, even in complex situations. **Official Response from Angela Heindl-Schober:** > Thank you, this is the shift we’re seeing across security teams. It’s no longer about more findings. It’s about validated, exploitable risk you can actually act on. That’s where human-validated testing makes the difference. We hear you on integration and are actively evolving the platform in that direction. As AI accelerates the attack landscape, prioritization and coverage become critical, which is exactly why we launched the Glasswing Readiness Assessment. Appreciate the partnership and the trust. Have a great day! Angela ### 4. Robust Pen Test Results with Clear, Insight-Rich Dashboards **Rating:** 5.0/5.0 stars **Reviewed by:** Scott S. | VP, Deputy Chief Information Security Officer, Enterprise (> 1000 emp.) **Reviewed Date:** April 06, 2026 **What do you like best about Synack?** The pen test results that come out of the service are very robust and always accompanied with detailed documentation enabling our teams to recreate the vulnerability. The dashboards and reporting provided within the platform are easy to digest and rich in data/insights. **What do you dislike about Synack?** It's more difficult to execute tests of internal applications that aren't exposed to the internet, though this is to be expected. In these cases, the Synack team works closely with us to set up the test using the best methods available. **What problems is Synack solving and how is that benefiting you?** application penetration testing at scale. It enables us to enforce expectations of timely pen testing on development teams using a cost-effective, light-weight setup framework. **Official Response from Angela Heindl-Schober:** > Scott — thank you for the thoughtful review. We really appreciate it. Great to hear the results and dashboards are delivering the clarity and insight your team needs. That combination of robust findings and actionable reporting is exactly what we aim for — helping teams not just identify vulnerabilities, but understand and validate real risk. You’re also right that testing internal applications can be more complex. We’re continuously working to make that process smoother and more effective, and it’s great to hear our team was able to support you in setting things up the right way. Thanks again for the partnership and for taking the time to share your experience. — Angela ### 5.

Indispensable for Independent Security Engagement **Rating:** 5.0/5.0 stars **Reviewed by:** Evan M. | Enterprise (> 1000 emp.) **Reviewed Date:** April 20, 2026 **What do you like best about Synack?** I really appreciate the Synack team's ability to engage independently, especially in our large federated environment. As the federal point of contact, it's great that they can work directly with organizations like NIH and CDC, finding ways to bring value with minimal guidance from me. I also find Synack's responsiveness impressive, as they always seem to find ways to add value. Setting up Synack was very easy, which is another thing I like about using it. **What do you dislike about Synack?** n/a **What problems is Synack solving and how is that benefiting you?** I use Synack for finding vulnerabilities across our environments and managing our VDP, which helps our team engage with independence. **Official Response from Kym Russell:** > Thank you for this! Operating in a large federated environment brings a unique set of challenges, and I’m so glad to hear our team has been able to provide value across organizations like NIH and CDC with minimal friction. Supporting that kind of independence and cross-agency responsiveness is a core goal for us. It’s great to see Synack is helping you bridge the gap between vulnerability discovery and VDP management. We’re committed to staying that reliable partner for you as your environment continues to evolve. - Kym ### 7.

Effective Pen Testing with Room for Onboarding Improvement **Rating:** 4.5/5.0 stars **Reviewed by:** James G. | Enterprise (> 1000 emp.) **Reviewed Date:** April 06, 2026 **What do you like best about Synack?** I like that the Synack platform is easy to use. It's great that developers can be in there in real-time, and the researchers can respond to their comments and vice versa. **What do you dislike about Synack?** The onboarding experience could be improved. There's a lot of effort on the initial onboarding as well as configurations and familiarity with the applications can be time-consuming. The initial setup of the applications for assessing is a little more cumbersome. **What problems is Synack solving and how is that benefiting you?** Synack helps us scale pen testing across a large enterprise by using vetted experts worldwide, ensuring high-fidelity findings. The bug bounty aspect motivates thorough testing. **Official Response from Angela Heindl-Schober:** > Dear James, thank you for the thoughtful review — I really appreciate you calling out the real-time collaboration between your team and the Synack Red Team. That’s exactly the kind of signal we aim to deliver: fast, high-confidence findings with direct interaction between developers and security experts. You’re also right to highlight onboarding. As we scale across complex enterprise environments, initial setup can require coordination — and we’re actively working to simplify and accelerate that experience.

There’s a lot of noise in the market right now, but what actually makes a difference is having people who think like attackers continuously putting pressure on your environment — not just once, but over time. Also good to hear your point on the edge cases. That’s real life. What matters is how fast things get picked up and resolved, and I’m glad the team stayed close and worked through it with you. That’s something we care a lot about. What’s interesting — and where things are evolving — is how we can extend exactly what you described. With Synack Sara, we’re able to cover more of the attack surface continuously, and then bring the human expertise in to validate what actually matters. It’s not about replacing what you’re seeing today — it’s about scaling it. Thanks again for the partnership — this kind of feedback is exactly what helps us keep improving. - Angela ### 10.
