# Security
The Ollama maintainer team takes security seriously and will actively work to resolve security issues.
## Reporting a vulnerability
If you discover a security vulnerability, please do not open a public issue. Instead, please report it by emailing hello@ollama.com. We ask that you give us sufficient time to investigate and address the vulnerability before disclosing it publicly.
Please include the following details in your report:
- A description of the vulnerability
- Steps to reproduce the issue
- Your assessment of the potential impact
- Any possible mitigations
## Security best practices
While the maintainer team does their best to secure Ollama, users are encouraged to implement their own security best practices, such as:
- Regularly updating to the latest version of Ollama
- Securing access to hosted instances of Ollama
- Monitoring systems for unusual activity
## Contact
For any other questions or concerns related to security, please contact us at hello@ollama.com
