We keep your Linux servers current and secure. Nothing happens without a test and approval. Everything is recorded.

Example

How an update runs.

  1. Hole found. Six servers affected.

  2. Dry run. Nothing changed yet.

  3. Approval. An engineer approves.

  4. Update. The same on all six servers.

  5. Logged. Cannot be changed afterwards.

The log

Immutable log with nightly backups, a critical vulnerability alert and the suggested fix
Every action goes into an immutable log: backups, alerts, approvals. Entries are chained and anchored with timestamps, so nothing can be changed afterwards.

Price

One fixed monthly price. After an assessment.
