An agentless alternative to Wazuh

If what you need from Wazuh is file change alerts, Alertica does that one job without a server, an indexer or agents. It connects over SFTP with a read-only login and alerts when files change, get deleted or never arrive. It's $20 per site a month on Pro, and there's a free plan that never expires.

Why teams pick Alertica over Wazuh

  • One job, no SIEM to run

    No server, indexer or dashboard to size, patch and back up. You add a server in the web app and the first scan runs the day you connect.

  • Nothing on the host to stop

    Alertica runs on our side and logs in from outside. An attacker on the host has no agent of ours to stop, and if the login stops working you get a Scan Failed alert.

  • Works where SSH doesn't

    Wazuh's agentless mode needs SSH from your Wazuh server. Alertica also connects over SFTP, FTPS or FTP, so it watches hosting accounts that never give you a shell.

  • Rules a web team wants

    More than 200 files deleted, a script in an uploads folder, a nightly export that never arrived. Pick them in the web app, with ready-made checks for common platforms.

Running in three steps

  1. Connect a server

    Add a server with an SFTP, FTPS or FTP login. Alertica only lists files, so a read-only login is enough. Nothing is installed.

  2. Set your rules

    Point a rule at a folder and say what matters: any change, more than 200 deleted files, a script where scripts don't belong, or no new export since yesterday.

  3. Get the alert

    Alerts go to the people you choose by email or SMS, with Slack coming soon. Every scan is kept in scan history.

What changes if you watch files with Alertica instead of Wazuh, and what doesn't.

Comparing for a specific audit? Tell us what it needs
  • Wazuh has agentless monitoring too. What's different?

    Wazuh's agentless mode runs from your own Wazuh server over SSH, and you add each host with a script on that server. Alertica is hosted, connects over SFTP, FTPS or FTP, and you add a server in the web app.

  • Does Alertica hash files the way Wazuh does?

    Not yet. Today it compares each file's name, size and modified time, and never opens the file. A content check is coming: it will fingerprint files on your own server over SSH where the host allows it, so it catches an edit that keeps the date and size, and only fingerprints leave the server.

  • Can I run Alertica next to Wazuh?

    Yes. Alertica only needs a login, so it adds a check from outside the host without touching your agents or your Wazuh server.

  • Does Alertica cover PCI DSS 11.5?

    Alertica does both things requirement 11.5.2 asks of a change-detection mechanism: it alerts when critical files are changed, added or deleted, and compares them at least once a week, daily on Pro. It compares file details rather than contents until the content check ships, so if your assessor wants hashes, keep a hashing tool on those hosts for now. It doesn't cover 11.6.1, the scripts on a payment page as the browser receives them.

  • Is it safe to give Alertica access to our servers?

    Yes. Alertica is agentless and read-only: it lists files and never opens, changes or deletes them, so a read-only login is all it needs. The logins you give it are encrypted with AES-256, and every Alertica account uses two-step sign-in.

  • What does Alertica cost?

    Free covers one site with weekly scans. Pro is $20 per site per month with daily scans, SMS alerts, and setup and onboarding with our team. Enterprise adds hourly scans and on-premises installation, priced by quote. Compare plans
