## Varonis security brief

- Perimeter-based email defenses miss AI-generated attacks that carry no obvious malicious link or attachment.
- A new report from Software Analyst Cyber Research (SACR) says email security must shift from detecting bad messages to investigating how an attack unfolds.
- SACR highlights Varonis Interceptor as an example of this shift because it uses an AI Phishing Sandbox that follows an attack through to the credential-harvesting page a user would actually land on.
