    Seamless Onboarding, Smart Cloud Scanning, and Exceptionally Helpful CSMs

    Reviewed on Jul 14, 2026
    Review provided by G2
    What do you like best about the product?
    The onboarding flow is seamless and straightforward. Synack’s software automatically scans our cloud infrastructure to identify what’s in scope, which makes setup much easier. The CSMs are incredibly helpful, responsive, and easy to work with. Synack’s missions also make testing simple by providing clear, checklist-based guidance.
    What do you dislike about the product?
    So far, I haven’t come across anything I don’t like about Synack.
    What problems is the product solving and how is that benefiting you?
    We were having trouble with our talent pool because they weren’t consistently up to date on the latest threats. Especially the AI-related issues. Synack's crowdsourced penetration testing model helps us mitigate this issue, and it allows us to address the newest vulnerabilities before attackers can target us.

    Trusted Testing with Powerful Analytics and Assurance

    Reviewed on Jun 30, 2026
    Review provided by G2
    What do you like best about the product?
    Synack gives me a safe and trusted environment to test assets with great controls and a great amount of data analytics to support. As a tester, it's a reliable and comprehensive platform to work on targets. The reporting is great, and I like the assurance that the assets are being tested thoroughly by a real world cohort of testers with lots of different skills and specialities. The platform highlights exactly where testing time is being focussed, which helps us ensure we're getting the coverage we think we are, and if not, we can specify particular areas for researchers to focus on. This means we're confident our assets have actually been tested, not just that we've been told they have been. We can identify trends and see which vulnerability type is occurring the most, which helps us understand where as a business we need to focus on improving our security posture and lets us focus the team's limited resources most effectively. The analytics dashboard that shows vulnerability locations and types is super valuable, and it makes it really easy for us to provide reporting to management to justify the spend and demonstrate the return we're getting. We valued the extra assurance we got from the vetted team of researchers, which is why we moved from HackerOne. The initial setup was really easy, we had a PoC and the sales team really made it simple. I'd rate it a 10 out of 10 to recommend.
    What do you dislike about the product?
    I honestly don't have anything bad to say about synack at this point.

    Indispensable for Independent Security Engagement

    Reviewed on Apr 20, 2026
    Review provided by G2
    What do you like best about the product?
    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 the product?

    What problems is the product 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.

    Synack’s Human-Validated Findings Help Us Prioritize and Cut Noise

    Reviewed on Apr 13, 2026
    Review provided by G2
    What do you like best about the product?
    Synack prioritizes real attackers with real validation. Our team relies heavily on outsourcing our pentesting to Synack because they help reduce noise. Synack’s findings are human-validated and exploitable, and that combination helps our infosec team prioritize efforts and focus on what matters most.
    What do you dislike about the product?
    Not natively integrated enough into the rest of your security stack. This solutions asks as a standalone and requires internal resources to maintain.
    What problems is the product solving and how is that benefiting you?
    Patch verification speeds up the process and provides real-world validation in real time.
