Bitdefender launches GravityZone email security for MSPs

Bitdefender has launched GravityZone Extended Email Security, which combines email and endpoint protection within the GravityZone platform.

The offering targets businesses and managed service providers that need to address threats arriving via email and remain active after reaching users' inboxes.

Email remains a major route for cyberattacks, particularly phishing, business email compromise, ransomware and impersonation attempts. Bitdefender aims to address this by combining secure email gateway filtering with post-delivery protection through an Integrated Cloud Email Security model.

The product is built on technology Bitdefender acquired through its purchase of Mesh Security and is offered as an add-on to existing GravityZone endpoint security deployments.

Email gap

Many email security tools focus on filtering messages before delivery, but attacks can still reach inboxes and remain undetected. Security teams also often use separate email and endpoint tools, creating gaps in visibility and slowing response when incidents spread from inboxes to user devices.

The new service is designed to inspect emails before delivery and continue monitoring them after arrival. If threats are identified later, the system can quarantine and remediate them.

It supports Microsoft 365, hybrid environments and other deployments. It can be deployed as a secure email gateway, while API-based and combined deployment models are also available for Microsoft 365.

Research cited by Bitdefender points to the scale of the problem. Business email compromise-related payments exceeded USD $6 billion in 2024, while 42 per cent of 1,200 IT and security professionals in a global survey identified business email compromise as the greatest threat to their organisation and 66 per cent reported an increase in such attacks.

MSP focus

Managed service providers are a key target market for the launch. The product includes centralised management, policy enforcement and workflows intended to support multi-tenant environments and distributed customer infrastructure.

Bitdefender is also positioning the product as a way to reduce the number of separate tools security teams use. By placing email and endpoint protection in the same platform, it aims to give administrators a single view of threats moving across the email attack chain.

This reflects a broader shift in the security market as vendors try to consolidate controls into fewer systems. For customers, the appeal is often simpler operations, quicker deployment and less manual work in day-to-day monitoring and response.

According to Bitdefender, integration with GravityZone allows organisations to add email security without deploying a separate platform. The company describes GravityZone as its unified security, risk analytics and compliance platform.

Andrei Florescu, President and General Manager of Bitdefender Business Solutions Group, outlined the company's view of the threat landscape and its response.

"Cybercriminals continue to rely on email as a primary attack vector, requiring organisations to adopt stronger, more integrated defences that reduce risk without adding complexity," said Florescu. "GravityZone Extended Email Security eliminates visibility and detection gaps across the full email attack chain, delivering powerful inbox protection before and after delivery to help organisations and MSPs stay ahead as attacks evolve."
