Darktrace / EMAIL Alternatives

Proofpoint Threat Protection does a genuinely solid job at keeping bad stuff out of your inbox, and that's the part you feel immediately as a user. Phishing attempts, suspicious links and weird attachments get filtered out before you even notice them, and the system is pretty good at catching the more subtle social-engineering emails that usually slip through other filters. You also get clear notifications when something is blocked and the explanations are usually straightforward enough for a basic user to understand why it happened. From a power-user perspective, the visibility is one of the biggest advantages. You can dig into message traces, see why a decision was made and get a decent picture of who in the organization is being targeted the most. It's not flashy, but it's reliable and once you know where everything is, it becomes a helpful part of your workflow. Integration with Microsoft 365 and Google Workplace is also smooth, so you don't spend days fighting with connectors or policies. That said, the platform isn't perfect. The interface feels old-school, and if you're new to it, you'll probably spend some time clicking around trying to find the right menu. Some actions that should be simple take more steps than they should. The cost is also on the higher side, and while the protection is strong, smaller teams might feel the price more than the value at first. And although the system is powerful, some of the advanced configuration options can feel a bit overwhelming until you get used to the logic behind them. Overall, Proofpoint Threat Protection delivers what most users actually care about: strong filtering, fewer dangerous emails and a sense that the system is doing its job quietly in the background. It's not the most modern or the easiest tool to learn, but once it's in place, it's dependable and effective.

From the start, we had a very good and knowledgeable pre-sales team who offered a thorough POC trial and nothing seemed to be too much trouble. Post sales support has also been good although I have not needed to use this much. The product itself is extremely capable and we have seen a vast improvement over our previous email security gateway. The risk of email threats has reduced significantly, but we have also had users comment on how clean their inboxes are as unwanted email can also be filtered out or diverted to a subfolder. Powerful dashboards, search tools and reporting provide valuable insight into the AI's detection capabilities and reasons why messages have been classified as a threat or otherwise. User interaction via reporting or quarantine reports is handled by an AI agent in the first instance and takes the pressure off the IT team as well as providing a good experience for the end user.

Mimecast goes beyond basic email security and actively adapts to threats as they come. Basic tools that allow admins to actively remediate threats are paramount to security and I have seen none that are simpler to use than what Mimecast offers. Most of what i have to say is glowingly positive but one criticism would be the organization of some things on the admin side is unintuitive but that learning curve is overcome quickly.

We've been a Barracuda customer for many years in our organisation and have approximately 80 users across three sites in three different countries under a single Microsoft tenant. It integrates cleanly with Microsoft 365 and has been stable and reliable over the years with only limited intervention required by IT when dealing with quarantined items and false positives.

The Knowbe4 Cloud Email Security, aka Knowbe4 Defend, in relation to Microsoft 365 - has a lot of setup involved, but luckily its almost all automated with a script that KB4 pre-built to connect the services in your Azure environment. The deployment team and the engineer we had ere very good, communicated well and timely, and the engineer knew how to fix certain pain points, which were mainly just customization options that we were choosing to enforce outside the regular deployment plan the provided to us. Once it was up and running, like any other AI tool, it takes time to learn your environment and then fine tune its detections. The dashboards and email notifications are exceptional.

We started looking into Abnormal to replace a more traditional email gateway solution that we had in place. We were spending a lot of time constantly maintaining block lists and sorting through false positives. We were spending a lot of time trying to tweak things to protect against incoming threats, only to have attackers switch tactics and eventually get through. It was a constant cat and mouse game, and we felt we were always behind. When we first deployed Abnormal and ran through a POC, we layered it on top of our existing solution. It was both impressive but also alarming as we quickly discovered the volume and extent of just what was coming through our traditional solution. Abnormal from the time we started the POC to full implementation Abnormal has just worked. I was amazed at just how easy it was to setup and configure as well as just how effective it's been. Abnormal has been truly transformative not only for my team, but our business as a whole.

We've used Sophos Email to strengthen the security of our corporate email, and the experience has been very positive. One of the areas where we've seen the most value is in reducing suspicious emails reaching end users, especially internal phishing emails and messages with potentially malicious links. Daily administration is simple, and the visibility into events makes it easy to track any email-related incidents.

It is an incredibly tough Secure Email Gateway that acts as a fortress for our inbound and outbound mail flow. It offers deep, granular inspection of payloads, though achieving the perfect balance between high catch rates and minimizing false positives requires dedicated, ongoing tuning.
