System requirements

Each part of a Deep Security deployment has its own system requirements.

Requirements vary by version. For older versions of Deep Security Manager, agents, relays, or virtual appliances, see their documentation.

If you plan to operate Deep Security in FIPS mode, see FIPS 140-2 support for additional requirements.

Deep Security Manager requirements

For a list of agent versions that are compatible with this version of the manager, see Deep Security Agent platforms.

System component Requirements
Minimum memory (RAM)

Minimum RAM requirements depend on the number of agents that are being managed. See Deep Security Manager sizing.


On Linux, reserved system memory is separate from process memory. Therefore, although the installer's estimate might be similar, it will detect less RAM than the computer actually has. To verify the computer's actual total RAM, log in with a superuser account and enter:
grep MemTotal /proc/meminfo
Minimum disk space 1.5 GB (200 GB recommended)
Operating system
  • Red Hat Enterprise Linux 8 (64-bit)
  • Red Hat Enterprise Linux 7 (64-bit)
  • Windows Server 2019 (64-bit)
  • Windows Server 2016 (64-bit)
  • Windows Server 2012 or 2012 R2 (64-bit)

If you are upgrading your Deep Security Manager and are currently using Windows Server 2008, we recommend that you add a new Deep Security Manager node on a supported operating system (see Install Deep Security Manager on multiple nodes). When that's complete, decommission the node running on Windows Server 2008.

Deep Security Agent requirements

The agent installer permits installation on any supported platform. RAM and disk space requirements are not checked.

Deep Security Relay requirements

Requirements are the same as those of the Deep Security Agent, with a few constraints:

  • Relays are only supported on 64-bit operating systems.
  • Relays are not supported on Solaris or AIX.
