In Deister we take the security very seriously. Periodically we enroll specialized companies to perform security assessments of our software platform.
The current Security Certificate has been issued on January 2018 by A2Secure and it states that the applications have a security level of Appropriate. No vulnerabilities have been found that could pose a risk to the application security, neither enabling a breach nor leading to an information leakage.
The full Security Assessment was conducted by the company A2Secure, through an automatic test using leading applications and manual validation according OWASP methodology. The test was performed for 27 hours against the applications hosted in https://www.mydeister.com and managed by Deister.
The certificate is available upon request.
