Payara Boosts Cybersecurity Credentials as CVE Numbering Authority

Fabio 3 (1)

Payara can now publish authoritative cybersecurity vulnerability information about its products via the CVE Program. Fabio Turizo, pictured, has been the leader of this initiative and says: “Becoming a CVE Numbering Authority creates an extra level of dependability for those using our products and continues our commitment in adhering to and maintaining the best possible security standards."

This is because vulnerabilities will now be part of the standardized and publicly disclosed CVE List, resulting in time and cost savings for those using Payara products. Security issues can be discussed, dealt with and prevented through use of a trusted, standardized catalogue.
