“Practical easy to deploy vulnerability scanning with strong cloud discovery”

5.0
Nov 5, 2025
We use Intruder to cover our external infrastructure and cloud accounts. Setup was very quick, onboarding friction was low and scans returned actionable findings with minimal tuning. Continuous discovery of internet facing services caught changes in our cloud footprint reliably and the risk priotisation meant we could focus on high impact fixes.

Intruder Likes & Dislikes

Like

Intruder's strengths for us are clear and practical: fast time to value and a clean UI that lets engineers run scans and triage issues without specialist training; built in cloud connectors (AWS/Azure/GCP) that automatically discover targets and integrations into our ITSM via an easy API.

Like

Ability to set up coverage for all of our services as defined targets, the emergent scanning that is frequently updated and automated. Any issues identified are clearly defined and accompanied by steps on how to remediate. Makes it very easy to stay at an A rating.

Like

- Very intuitive and clear UX. - Spot on solution for startups and early (in development) products. - Expand the coverage of penetration testing as you go. - Fast to get started and get insights.

Dislike

Exports and compliance grade Reports aren't as flexible as some other platforms. Feature depth for very large complex Environment.

Dislike

While the reporting and dashboards are good, they could be improved upon. Exporting data out of the system could also allow for more filtering and I would like to see longer data retention.

Dislike

- Authentication set up is a bit clunky. Hopefully the documentation is helpful and it allows you to set it up properly. Ideally all of the docs and guidance would be in-product.

    Intruder - Autopenetration Testing for Startups and SOC2 Kick off

    4.0
    Oct 28, 2025
    - Simple to use. - Autopentests are a requirement to the SOC2. Intruder platform offers a solid base to start this. Early products (startup products) do not require customized and tailored penetration testing which costs much more.
