Inside the Integration: What GravityZone + Mesh Means for Bitdefender Customers

Bitdefender GravityZone customers are gaining a more unified, scalable, and complete cybersecurity stack—from endpoints to inboxes—thanks to Bitdefender’s recent acquisition of Mesh email security.

Now, Bitdefender GravityZone Extended Email Security will deliver comprehensive protection by uniting advanced CAPES (Cloud-native, API-enabled) defenses with a secure email gateway (SEG) in a single, integrated solution. This dual-layered approach protects your organization against today’s most advanced threats, including ransomware, phishing, and business email compromise (BEC).

Q&A Discussion About the Integration

Following the completion of the acquisition, I sat down with Mesh Co-Founder Brian Byrne and Bitdefender Vice President of Products, Daniel Daraban, to learn what makes Mesh such a powerful solution, and to explore the security outcomes Bitdefender customers and partners, like MSPs, can expect.

Q: The email security market is crowded. How does Mesh approach the email security challenge differently from others? Why is this beneficial to Bitdefender GravityZone customers?

A: Brian Byrne
“At the highest possible level, Mesh prevents malicious and unnecessary emails from reaching employees for businesses of all shapes and sizes around the globe.

We created mesh when most providers focused on API-based email security products. In that use-case, the email must reach the mailbox before the product sees it, scans it, and then stops it if it's dangerous. This presents a potential security risk; and in response, we noticed some organizations and MSPs (managed service providers) doubled up on tools. They would use a secure email gateway and layer that with an API based solution, believing they had the best of both worlds.

The downside was managing two separate email security solutions: two UIs (user interfaces), two places to onboard and off-board users and clients, two security vendors to pay, two places to investigate after each support ticket. ‘Hey, I'm expecting this email. I don't have it in my mailbox; can you check on this?’ The help desk would log into one solution and find that it wasn’t there, so they’d have to log into the second solution to locate and release it.

Mesh solves these issues by providing both secure email gateway (SEG) and mailbox-level detection via API-based deployment in a single solution, addressing security gaps that existed with traditional approaches. This is now being integrated into Bitdefender GravityZone.”

Q: I’ve also heard you mention this is very powerful for MSPs. How so?

A: Brian Byrne
“We also founded Mesh to simplify email security in another way, especially for those with multi-tenant environments. For example, for an MSP managing 100 customer tenants, instead of needing to log into every individual end customer to make a change, we enable them to take action for a single mailbox and apply that same action to every mailbox across every customer if desired. This holistic approach lets MSPs treat their collective customer base as one big community and easily protect them at the same time.”

Q: Daniel, we’ve established why Mesh email security is unique and how the acquisition makes sense. Now, will you share, at a high level, what this integration will mean for GravityZone customers?

A: Daniel Daraban
“With Mesh integrated into GravityZone, Bitdefender customers benefit from a combination of advanced CAPES (cloud-native, API-enabled) protection with a secure email gateway (SEG) in a single solution. This leads to positive security outcomes by safeguarding organizations against sophisticated email-based attacks, including ransomware, phishing, and business email compromise (BEC). However, there are many other benefits.

In every incident, context is key. With this integration, GravityZone customers will rapidly expand their visibility into email-based attacks through increased context.

For example, if I am looking at an incident and want to understand what happened at the organizational level, the data I am already gathering from various endpoints, including the cloud and network, is now paired with what I'm getting from the Mesh integration in GravityZone. This gives me 360 degrees of visibility into what happened and why this incident was triggered. I can rapidly answer questions like, ‘Did this spread within the organization, and if so, how?’ Or, ‘Did someone try to do something, and it just went through one security layer, only to be picked up by the next one and stopped?’

This significantly simplifies threat mitigation and incident response by reducing the need for console hopping or context switching.

And IT and security teams will now gain instant peace of mind because this integration enables GravityZone to perform more actions right out of the box. The GravityZone unified platform, after the Mesh integration, is even more powerful than it was before.”

Q: Gartner recently published an extensive report on the evolving cybersecurity landscape in 2025 that offered strategic recommendations for cybersecurity leaders, and stated the following:

“By 2027, cybersecurity organizations that unite email security, endpoint security and SSE tools in a workspace security platform will experience 50% fewer successful cyberattacks than peers using siloed solutions.”

Q: How does the Mesh security acquisition deliver on this?

A: Daniel Daraban
“We believe creating this visibility for our customers, and having all of these email-related datapoints, puts us in a top position to fulfill the vision and approach that Gartner is recommending for organizations. We will provide deep context and dual methods of protection against email threats in a single unified platform, GravityZone. We are looking forward to powerful outcomes as Bitdefender customers and partners realize the many benefits of this integration.”
