Free Cyber Security Tools

The U.S. cybersecurity agency, CISA has recently compiled a list of Free Cyber Security Tools and services for the organizations through which they can efficiently increase their security and defend against several cyberattacks.

The list that is provided by the CISA contains open source tools and services only from both public and private organizations.

While CISA has asserted that they will keep updating their list since it’s an active living project. Even they will also allow third-party organizations to nominate their tools and services for the inclusion of their tools on this list of CISA.

Here’s what the Director of CISA, Jen Easterly stated:-

“CISA is super proud to announce the start of a new catalog of free resources available to those critical infrastructure owners and operators who would benefit from tools to help their security and resilience. Many organizations, both public and private, are target-rich and resource-poor. 

“The resources on this list will help such organizations improve their security posture, which is particularly critical in the current heightened threat environment. This initial catalog will grow and mature as we include additional free tools from other partners.”
