Should your enterprise embrace open source cybersecurity tools? What can free and open source cybersecurity tools offer your enterprise? Also, what open source cybersecurity tools exist for the three major branches of business InfoSec: Identity Management, Endpoint Security, and SIEM?
Open source cybersecurity tools, as the name suggests, open their cybersecurity designs to the public for easy modification and customization. Therefore, your IT security team could deploy one of these tools and modify it to fit your organization’s use case.
Additionally, almost all open source cybersecurity tools are free to use, which can help enterprises save on their IT budgets. During the coronavirus pandemic and the era of social distancing, this could certainly appeal to businesses of all sizes.
However, these tools don’t offer the same functionality, capabilities, or optimal performance of a full-fledged solution. For example, open source identity and access management can’t offer the capabilities of full identity governance or privileged access management solutions. At the same time, these tools could help bridge gaps while you seek out a more robust solution or while you sort your cybersecurity budget.
Thus, Solutions Review presents the top 30 free and open source cybersecurity tools.
Open Source Cybersecurity Tools
This stands as perhaps one of the most well-known open source identity management tools; it features single sign-on, user and group management, flexible authentication, and automated provisioning—a major component of identity governance and administration. Moreover, OpenIAM aims to help reduce enterprise operational costs and improve identity audits via a centralized control station. Also, the community version doesn’t enforce a time limit on subscriptions and benefits from community forum support.
Finally, there are different tools for different enterprise identity management needs, including OpenAM and OpenIG.
2. Apache Syncope
The Apache Syncope platform describes itself as an open source system managing digital identities in enterprise environments; it rarely gets more straightforward. Apache Syncope focuses on providing identity lifecycle management, identity storage, provisioning engines, and access management capabilities.
