In May 2024 we are releasing new versions of Countercept Agents for Windows, Linux and Mac platforms. Managed clients will get all these changes automatically. A little later we will publish new release groups to switch clients using managed updates in collaboration with the WithSecure Engagement team.After the upgrade new versions of Countercept Agents will start using new addresses. <\/p>\n

For many customers, WithSecure products will function correctly without needing to know which servers the products connect to.<\/p>\n

However, some administrators tightly control which network addresses they allow their clients to connect to (\u201cEgress control\u201d or \u201coutbound connections\u201d), and it is\u00a0mandatory<\/strong>\u00a0that they allow connections to the following addresses. WithSecure cannot guarantee the functionality of the products if access to these addresses is blocked.<\/p>\n

The product may not function correctly if access to these network addresses is not allowed.<\/strong><\/p>\n

Please note that all the following require outbound connections to TCP\/443 unless otherwise stated.<\/p>\n

Additionally, any products listed in this document also includes F-Secure branded versions of the same products.<\/p>\n

Recommendations<\/h2>\n

WithSecure recommends, where possible, that administrators allow outbound access to all address under the withsecure.com and fsapi.com domains. We do appreciate that this is not always possible due to firewall configuration limitations, or even from an operational perspective, so we are publishing an explicit list of server addresses.<\/p>\n

Please note that\u00a0we do not guarantee<\/strong>\u00a0this list of addresses is complete or will stay unchanged, so we strongly recommend bookmarking these articles for future reference. We will update these articles whenever needed.<\/p>\n
