KB-2336 March 2025 Security Update

Appian is aware of reports of an alleged suspicious activity involving one of its customers. At this time, we are not aware of an impact to Appian products, the Appian Cloud Platform, or any other Appian instances.

Appian continues to remain proactive in monitoring the situation and is collaborating with the potentially affected customer. Appian actively monitors the security of its products and cloud platform.

We advocate for organizations to take a proactive approach to security configuration, including those associated with Appian Protect. The following are some recommended steps where applicable and in accordance with organizational security policies:

Enforce Multi-Factor Authentication on all accounts;
Set up Network Policy Rules to only allow traffic from trusted locations (VPN, AWS Private Link, Trusted IPs, etc.); and
Customers are encouraged to monitor the logs from their Appian instances via the Log Streaming feature, and integrate this telemetry into a SIEM or other monitoring security tool.
