Why Businesses Choose Heimdal

Heimdal’s All-in-One Email & Endpoint Security with an Easy Dashboard

What do you like best about Heimdal? I like that Heimdal integrates the most commonly used apps, which helps organizations stay secure. The dashboard is easy to learn and understand, and support is always available when needed. The program performs its main function of isolating bad emails and links 100% of the time. We chose Heimdal over other products because it provides both email and endpoint security in one bundle. The pricing is very attractive because of the bundle, and I only have to deal with one vendor when issues arise. What do you dislike about Heimdal? Nothing at the moment. As an organization, we’ve used most of its features, and we’re happy with it overall.

Effortless Patch Management, Reliable Security

What do you like best about Heimdal? I really appreciate Heimdal® for its patch management ease, which makes my job simpler. I'm also able to ensure all devices are free of typical vulnerabilities. Plus, the initial setup was very easy, which was a relief. What do you dislike about Heimdal? I find DarkGuard DNS sometimes stalls and is unreliable at times.

Reliable, simple and flexible.

What do you like best about Heimdal? It just works. We use Patch Management, E-mail Security and Remote Desktop modules from the Heimdal portfolio. All these products run through a single agent and consistently perform well. We push Microsoft patches every month to clients and servers without issue (and more reliably than something like WSUS) , Remote Desktop is simple to use as an admin, just right-click the agent search for the user you want to connect to and go, and E-mail Security Spam filtering catches the majority of the bad things. Heimdal also creates a decent asset register for each device you install the agent on. Support is also responsive and helpful, normally coming back with an answer in only 30 minutes! What do you dislike about Heimdal? First time setup can be a little challenging. Patch management group policies took a little bit of getting used to the way Heimdal uses its terminology but once you crack it, it just ticks along. Spam filtering could be a little more flexible, the previous product we used was able to manage allow/deny lists per user. Heimdal takes a more global approach so you tend to be allowing an email for the entire domain. A little more control of client machines would be helpful. Some alternative products allow you to force a reboot for instance.

Great 3-party patchmanagement

What do you like best about Heimdal? We have used Heimdal security for many years now. We have tried most of their offerings. Now we use patch management of 3-party applications and email protection and Network threat prevention. The products are great and simple to use. Especially the 3-party application patch management has saved us hours of work. What do you dislike about Heimdal? The portal can be a bit messy to look at, and it has changed a couple of times over the years. The report on ROI does not make sense. Difficult to estimate the cost of traffic blocked.
