Automated threat detection that protects against corruption with minimal intervention
Abnormal Security is valuable because it features an automated scoring tool that doesn't require much intervention from our team. It enhances threat detection capabilities by making the process automated and is easy to scale to our entire environment. Additionally, it protects us from being business email compromised, which is invaluable for maintaining our security.

Provides valuable security features and has a straightforward setup process
The initial setup process is straightforward and takes a weekend at most. A .com domain can take up to forty-eight hours, while a local domain takes about four to eight hours because it has to propagate through the international DNS records. It is a cloud-only solution. If you're managing email security on-premises, you use your bandwidth to download emails, including spam, and then use your servers to clean it up. For example, say a third of your email is spam; this consumes significant bandwidth and resources. However, if you use Mimecast, they filter the emails on their servers before delivering them to you. It can be a major selling point in regions with expensive bandwidth, such as Africa. You can save bandwidth and improve overall efficiency by offloading the spam filtering to Mimecast.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Initial auto-remediation allows us to auto-remediate before the email lands in the end user's inbox for a split second."
"I have never encountered any stability issues with Abnormal."
"The features that appeal to me most are the combination of auto-remediation and Detection 360."
"It does some really cool stuff that other tools aren't doing. We found it to be really effective, and the AI/ML functionality is really what differentiates them."
"I would recommend Abnormal Security."
"Their ability to take things out of the mailbox and catch things much faster than users is excellent."
"What I like about Abnormal Security is that it notifies me if any of my partners or suppliers are experiencing a security breach by analyzing their database and identifying potential cyber threats."
"It protects us from being business email compromised, which is invaluable for maintaining our security."
"The interface of this solution is very easy to navigate and user-friendly. There is no delivery in email and other communications, making it reliable. The configuration is relatively easy."
"In terms of efficacy, Proofpoint is better than Mimecast, though it's a little difficult to manage."
"It's really quite user-friendly. In terms of technical superiority and the product itself, there are no complaints. It is really cutting edge."
"URL inspection works pretty well."
"The product's most valuable features are impersonation protection and phishing countermeasures."
"The solution is scalable."
"It's good, it keeps the spam out."
"We like Mimecast's spam filtering. The email signature feature is also a big plus for our users."
 

Cons

"There could be room for improvement in enhancing integration with other cybersecurity tools."
"The ideal scenario would be for Abnormal Security to work in tandem with Microsoft to analyze incoming emails."
"I would like to have the ability to customize the auto-remediation feature."
"There could be more selectable options and more granular selections available."
"One feature I'd love to see is outbound scanning."
"The biggest pain point for us is the lack of support for on-premise email systems."
"I, as such, do not have anything that I do not like or would like to add, but you could argue that because they are doing it API-based, there is a chance that something could slip through temporarily before they are able to pull it out. In theory, it could happen just because of the nature of the system. They are not in line with the delivery of the mail. They are kind of asynchronous, which is a pro as well as a con. If it is synchronous, then I know it would always stop them, but because it is asynchronous, things could get through temporarily or because of some system issues on the Microsoft side or their side. It is the nature of the beast, but it is a little bit of a con."
"When we're working on something as engineers, and we find an idea or a method of doing something that would be greatly improved by doing it another way, there should be an ability for me to click the ideas button, type in an idea that I have, and submit it to a product review team or developers to have them think through the process a little bit more."
"Its pricing can be improved. It is a bit expensive."
"We have subscribed to an archival service, and yet, when we have to get our data out, we have to pay a fee to get our own data. They charge an extraction fee."
"Their support should be improved. They are notorious for sending you to knowledge-based articles rather than actually talking to you, but that is, unfortunately, kind of becoming a trend with everything. In terms of features, I haven't had any complaints. However, I don't like the fact they moved to a paid training subscription model. They used to have a lot of free webinars for training, but they have started to charge for them in the past year."
"The detection rates are an area for improvement."
"Mimecast need to ensure that the body text format is correctly handled and that images are properly embedded in the body text."
"I did have a problem with Mimecast. That is why I was looking for an alternative solution because their sender IP address gets poorly rated by Microsoft."
"From an administrative point of view, Mimecast is a little bit cumbersome and difficult. It's not something that the end-user can easily find navigate themselves."
"They could provide a unified licensing model, including all the security features."
 

Pricing and Cost Advice

"The pricing appears fair, and they demonstrate a genuine willingness to work with us on it."
"The license is based on the user count, so the number of users that have an email address in the organization."
"Abnormal Security, on the other hand, provides the same level of functionality for just over $60,000 – that's half the price!"
"Overall, we'd certainly prefer lower pricing, but Abnormal Security doesn't seem unreasonable compared to similar offerings in the market."
"The product has good pricing in terms of return on investment."
"Compared to the other solutions in the market, Mimecast Email Security with Targeted Threat Protection's pricing is fine."
"I'm always going to say the price needs to be lower, but it's reasonable."
"It is a bit expensive."
"The solution is expensive."
"There are additional costs beyond the standard licensing fee."
"It's an expensive solution."
"The product price is moderate. I rate the pricing a five out of ten."
