"Best tool to audit your active directory"

5/5

What do you like best about Semperis Purple Knight?

Although there are numerous tools capable of auditing Active Directory, Purple distinguishes itself by not only conducting audits but also offering detailed explanations for every vulnerability it uncovers. Additionally, it provides clear guidance on how to address these issues.

Purple knight is also easy to implement, it leads you to give the missing permission, and is running pretty quick

And the best of it, the tool is free, thank you Semperis. Review collected by and hosted on G2.com.

What do you dislike about Semperis Purple Knight?

Because Purple Knight is offered as a free tool, I honestly have no complaints to make. Review collected by and hosted on G2.com.

What problems is Semperis Purple Knight solving and how is that benefiting you?

Purple Knight audits your Active Directory and guides you in addressing well-known vulnerabilities. This has been beneficial for me, as I am responsible for securing our Active Directory as a system administrator. It's impossible to be aware of every vulnerability or know exactly how to manage each one, so having this tool has been very helpful. Review collected by and hosted on G2.com.

"Absolutely Love This Software!"

4.5/5

What do you like best about Semperis Purple Knight?

Most Helpful Aspect:

It provides an immediate, prioritized list of your most critical Active Directory security gaps for free. This tells you exactly what to fix first to stop attackers.

Key Upsides:

It's a free and extremely easy-to-use tool that quickly translates complex Active Directory risks into a clear, actionable report. Review collected by and hosted on G2.com.

What do you dislike about Semperis Purple Knight?

Least Helpful Aspect:

It is a snapshot-in-time assessment tool, not a monitoring solution. It identifies problems but cannot continuously monitor for new threats or automatically remediate the issues it finds.

Key Downsides:

The report can be overwhelming without expert knowledge to interpret it, and it provides no automated fixing—all remediation must be done manually by your IT team. Review collected by and hosted on G2.com.

4.5/5

What do you like best about Semperis Purple Knight?

Purple Knight is fast, free, and highly effective for identity security assessments, making it a great first step for organizations to uncover AD and Entra ID weaknesses before attackers do Review collected by and hosted on G2.com.

What do you dislike about Semperis Purple Knight?

It only provides point-in-time assessments and lacks continuous monitoring or real-time alerts.

There is no automated remediation, so all fixes must be applied manually.

Reports are basic and static, with no trend analysis or advanced dashboards.

Requires manual setup for Entra ID scans, adding complexity for hybrid environments.

Does not integrate with SIEM/SOAR platforms for centralized security operations. Review collected by and hosted on G2.com.
