Endpoint protection

To protect your network with Bitdefender, you must install the GravityZone security agents on network endpoints. For optimized protection, you can also install Security Servers. For this purpose, you need a Control Center user with administrator privileges over the services you need to install and over the network endpoints under your management.

Requirements for the security agent are different, based on whether has additional server roles, such as Relay, Exchange Protection or Patch Caching Server. For more information on the agent's roles, refer to this section.

Important

Make sure that the HKLM\SYSTEM\CurrentControlSet\Policies\EarlyLaunch\DriverLoadPolicy registry key is set to any value other than 8 = Good only.

Security agent with Relay role

The Relay role needs hardware additional resources to the basic security agent's configuration. These requirements are to support the Update Server and installation packages hosted by the endpoint:

Number of connected endpoints	CPU to support Update Server	RAM	Free disk space for Update Server
1 - 300	minimum Intel® Core™ i3 or equivalent processor, 2 vCPU per core	1 GB	10 GB
300 - 1000	minimum Intel® Core™ i5 or equivalent processor, 4 vCPU per core	1 GB	10 GB

Warning

Relay agents require SSD disks, to support the high amount of read/write operations.

Important

If you want to save the installation packages and updates to another partition than the one where the agent is installed, make sure both partitions have sufficient free disk space (10 GB), otherwise, the agent aborts the installation. This is required only at installation.
On Windows endpoints, local to local symbolic links must be enabled.

Security agent with Exchange Protection role

The quarantine for Exchange Servers requires additional hard-disk space on the partition where the security agent is installed.

The quarantine size depends on the number of items stored and their size.

By default, the agent is installed on the system partition.

Security agent with Patch Caching Server role

The agent with Patch Caching Server role must meet the following cumulative requirements:

All hardware requirements of the simple security agent (without roles)
All hardware requirements of the Relay role
Additionally 100 GB of free disk space to store the downloaded patches

Important

If you want to save the patches to another partition than the one where the agent is installed, make sure both partitions have sufficient free disk space (100 GB), otherwise, the agent aborts the installation. This is required only at installation.

The following table indicates the number of simultaneous connections supported by a machine that has only the Patch Caching Server role installed.

Number of connected endpoints	CPU to support Update Server	RAM	Free disk space for Update Server	Disk type
1 - 500	minimum Intel® Core™ i3 or equivalent processor, 2 vCPU per core	2 GB	100 GB	SSD
500 - 1500	minimum Intel® Core™ i5 or equivalent processor, 4 vCPU per core	4 GB	100 GB	SSD

Important

Bitdefender performed the tests using machines running Ubuntu 20.04 LTS and Windows Server 2016.
For machines that have other roles installed in addition to Patch Caching Server, you must consider allocating more hardware resources.

Security Containers

Configure the guest operating systems where you are deploying BEST as follows:

Resource	Minimum	Recommended
Processor	2 vCPUs	4 vCPUs
Memory (RAM)	4 GB RAM	6 GB RAM
Free Disk Space	2.5 GB (up to 4 GB disk with debug logs enabled)	4 GB

Certificate prerequisites

The following is a list of prerequisites for installing Bitdefender Endpoint Security Tools for Windows:

Import the DigiCert Global Root G2 certificate. It must be imported as a trusted certificate by following these steps:
1. Download the DigiCert Global Root G2 certificate.
2. Press Win + R to open the Run window.
3. Type mmc and click Ok. This will open the Microsoft Management Console (MMC) window.
4. Go to File > Add/Remove snap-in.
5. Select Certificates and click Add.
6. Select Computer account and click Next.
7. Select Local computer and click Finish.
8. Click Ok.
9. Go to Console Root > Certificates (Local Computer) > Trusted Root Certification Authorities.
10. Right click Certificates > All tasks > Import > Next.
11. Navigate to the folder where the DigiCert Global Root G2 was downloaded and select it.
12. Click Next until the setup wizard is completed.
13. Close the MMC window and select No when prompted to save any changes.

Enable SHA256 certificates. Without them, the installer does not work at all. For more information, refer to the Microsoft Security Advisory 3033929.
Make sure your root certificates are up to date:
- Bitdefender certificates
- Timestamp certificates: we generally use Symantech/ Digicert
If the trusted signature is invalid, make sure Automatic Root Certificate Updates are enabled:
1. Open the Run command window, type gpedit.msc and press Enter
2. Select Computer Configuration > Administrative Templates > System > Internet Communication Management > Internet Communication Settings
3. Double click Turn off Automatic Root Certificates Update and select the Disabled option.
4. Open Command Prompt with administrative right and run the following command:
  certutil -setreg chain\ChainCacheResyncFiletime @now
In addition, you can manually add the following Digicert certificates, from the Official DigiCert Trusted Root Authority Certificates page:
- DigiCert Global Root CA
- DigiCert Assured ID Root CA
- DigiCert SHA2 Assured ID Code Signing CA
- DigiCert Trusted Root G4
- DigiCert Trusted G4 Code Signing RSA4096 SHA384 2021 CA1
- VeriSign Universal Root Certification Authority
Enable the Universal Microsoft C Runtime (UCRT) component. The UCRT is available by using Windows Update on older operating systems that are still in extended support. Alternatively, you can find the updates through the Microsoft Download Center.
If the following error occurs, your system is out of date:
Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source.
Note
This only applies to Windows 7 and Windows Server 2008 R2 machines.

Compatibility with container infrastructure

The following infrastructure is supported:

Amazon ECS, except serverless deployments
Amazon EKS
Google GKE
Docker
Podman
Kubernetes
Azure AKS

Memory and CPU

The memory and CPU resource allocation for the Security Server depends on the number and type of VMs running on the host. The following table lists the recommended resources to be allocated:

Consolidation	Number of protected VMs	RAM	CPUs
Low	1 - 30	2 GB	2 CPUs
Low	31 - 50	4 GB	2 CPUs
Medium	51-100	4 GB	4 CPUs
High	101-200	4 GB	6 CPUs

HDD Space

You must provision 8 GB disk space on each host of the Security Server.

Security Server distribution on hosts

Although not mandatory, Bitdefender recommends installing Security Server on each physical host for improved performance.

Network latency

The communication latency between Security Server and the protected endpoints must be under 50 ms.

Storage Protection load

The impact of Storage Protection on Security Server when scanning 20 GB is as follows:

Storage Protection status	Security Server resources	Security Server load	Transfer time (mm:ss)
Disabled (baseline)	N/A	N/A	10:10
Enabled	4 vCPU 4 GB RAM	Normal	10:30
