A security layer on top of Proactive.
The High Security Add-on sits on top of Proactive Managed Services. It adds host-based security monitoring, vulnerability scanning, penetration testing, firewall audits, access auditing, and a monthly security report to a named list of Linux servers. High Security comes with the Managed Detection and Response (MDR) Add-on.
The list can be every server in your proactive scope or a subset. Servers not on the list receive Proactive services only. All Proactive services on the covered servers continue unchanged.
The monthly security report includes extended security metrics and CVE results. Critical findings are escalated outside the reporting cycle.
The High Security Add-on attaches to this scope and applies only to the servers listed under it.

Why teams add High Security
Visibility into what happens on each server
- Security events on each covered server collected and correlated in one place
- Changes to important files picked up
- Rootkits, anomalies and intrusion attempts detected
- History kept, so there's something to look at when you need it
Known vulnerabilities found and triaged
- Installed packages checked against published vulnerabilities
- Findings triaged into your monthly security report
- Critical findings escalated immediately
Your servers and their boundaries tested
- Vulnerabilities, misconfigurations and human error found much sooner than a once-a-year test would
- Covers your covered servers and the network boundaries directly around them
- Firewall and load balancer rules reviewed for least privilege and kept documented
Access you can account for
- The stray account that doesn't belong, and accounts with more access than they need, found on your covered servers (root, sudo and SSH keys)
- Security results in your monthly report, alongside your standard report
- Critical findings escalated outside the reporting cycle
When this add-on makes sense
What this add-on works with
Very often paired with High Security. The NOC add-on gives your covered servers round-the-clock emergency coverage, with a 1-hour response commitment on critical issues.
Read about the 24/7 NOC Add-onIncluded with High Security. A Security Operations Center (SOC) watches your covered Linux servers around the clock, so detection turns into response at any hour.
Read about the MDR Add-onAlways included, then what is optional.
Everything here applies to the servers listed under the add-on. All Proactive services on those servers continue unchanged.
