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.

  • Microsoft SQL Server Express is only supported in very limited deployments. See Microsoft SQL Server Express considerations.
  • Microsoft SQL Server service packs for these versions are also supported.
  • Microsoft SQL Server is only supported when database containment is set to NONE. For details, see this Microsoft webpage on contained databases.
  • Oracle Database Express (XE) is not supported.
  • Oracle container database (CDB) configuration is not supported with Deep Security Manager multi-tenancy.
Web browser

Cookies must be enabled.

We recommend using the latest version of these browsers:

  • Firefox
  • Microsoft Internet Explorer 11 or Edge
  • Google Chrome
  • Apple Safari on a Mac

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.

Deep Security Virtual Appliance requirements

Because the appliance uses the same protection modules as agents, if you import an update to the 64-bit agent for Red Hat, it may notify you that new software is available for the appliance, like it does for Red Hat agents.

VMware does not support running nested ESXi servers in production environments. For more information, see the VMware Knowledge Base article.
System component Requirements

64-bit, Intel-VT or AMD-V present and enabled in UEFI.

The number of CPUs varies by the number of VMs being protected. See Deep Security Virtual Appliance sizing.

Minimum memory (RAM)

Varies by the number of VMs being protected. See Deep Security Virtual Appliance sizing.

Minimum disk space Varies by the number of VMs being protected. See Deep Security Virtual Appliance sizing.

VMware NSX-T Data Center (NSX-T):

  • VMware vCenter 7.0 with ESXi 7.0
  • VMware vCenter 6.7 with ESXi 6.7 EP06 (release name ESXi 670-201901001)
  • VMware vCenter 6.5 with 6.5 U2 P03 (release name ESXi 650-201811002)
  • VMware NSX-T 3.x*

*VMware NSX-T 3.x is required to use the appliance in DPDK mode.

VMware NSX Data Center for vSphere (NSX-V):

  • VMware vCenter 6.7 with ESXi 6.7
  • VMware vCenter 6.5 with ESXi 6.5
  • VMware NSX Manager 6.4.x
    VMware vSphere 6.5a is the minimum supported version with NSX for vSphere 6.4.0 and later.

VMware vCloud Director:

  • supported with VMware NSX Data Center for vSphere (NSX-V) only
  • versions up to and including 9.5 are supported

For details, see the VMware compatibility matrix.

For more information about VMware product interoperability, see VMware Interoperability Matrices.

vCloud Networking & Security (vCNS) is not supported.


The chosen vSwitch of the appliance must be able to communicate with the manager at the management network level. It can be any one of the following types:

  • vSphere Standard Switch (vSS)
  • vSphere Distributed Switch (vDS)
  • NSX-T Virtual Distributed Switch (N-VDS)
Guest VMs

The VMs (guests) that will be protected by the virtual appliance have these requirements:

  • Supported operating systems: See Deep Security Virtual Appliance 20 (NSX) supported guest OS's.
  • Compatible vSphere versions: See this VMware Compatibility Guide.
  • Required drivers: If you plan to enable Anti-Malware protection through the virtual appliance, you must install the Guest Introspection Thin Agent with the File Introspection driver (vsepflt) on each guest. For installation instructions, see your VMware NSX-V documentation or NSX-T documentation and search for Install the Guest Introspection Thin Agent.
  • To use Network Introspection (E-W) with NSX-T, the VMs (guests) must be linked to one of the following switches:

    • NSX-T Virtual Distributed Switch (N-VDS)
    • vSphere Distributed Switch (vDS) - new in vSphere 7.0:
      • vDS 7.0 requires NSX-T 3.0, vCenter 7.0 and ESXi 7.0 or later
