Security auditing and Vulnerability management

To continuously assure a reliable and secure product for its customers, Siteimprove has its application suite tested for security vulnerabilities, both internally and externally.

Internally, this is done through quality checks before each release as well as 'bug hunting' sessions, where Siteimprove developers will try out new features in order to discover if the application is not responding as it should. 

Externally, this is done by a 3rd party entity that specializes in penetration testing services. The process concludes with a vulnerability report which will serve as input for the development of the application. This process is repeated every 6-9 months to verify that previously discovered vulnerabilities have been fixed and to uncover new vulnerabilities. The detailed vulnerability report as well as the detailed plan for fixing the vulnerabilities will not be shared with external parties due to the confidentiality of its contents. Siteimprove can provide to customers, upon request and a signed NDA, a high-level summary proving the fact that the penetration test has been done by a 3rd party entity.
