Mimecast Review

Mimecast is a top cybersecurity provider helping organizations globally make email safer and reinforce cyber resilience without high cost and complexity. Is it the best option for your business, though? Read our Mimecast review to find out where the company stands in the industry and learn more about its offering, customer service, and prices. 


Granular Services that Keep Your Inbox Safe

Founded in 2003 in London, Mimecast expanded its operation globally, with 12 offices and 1,700+ employees. With 38,000 customers, 337 billion emails under management, and a 95% retention rate, the company lives up to its promise to become a long-term partner. 

Mimecast’s core is its proprietary cloud architecture, which translates into comprehensive security, archiving, and continuity into one service. The team provides security controls before, continuity during, and automated recovery after an attack. 

Mimecast’s services can be installed on individual or multi-user machines. The options include installing using group policy, a system center configuration manager, or a click-to-run license. 

The research for this Mimecast review showed that if we compare Mimecast vs Proofpoint for example, the former falls short in terms of UI. If you’re looking for sleeker UI, Proofpoint is a better choice. Mimecast, however, leads the way with its constant innovation, accuracy, and excellent customer service.

Mimecast email security offers protection even from the most sophisticated attacks. The Email Security 3.0 integrates three protection zones—one at your email perimeter, another inside your network and organization, and a third beyond your perimeter.

What customers appreciate the most about this service is rewriting URLs in inbound emails and real-time scanning. Additionally, the service blocks commonly exploited typo squatted interned brands, strips of file attachments that contain malicious URLs, and customizable user education.

Mimecast Spam Filter Review

Mimecast’s archiving, continuity, and security solutions are combined into one platform that provides email risk management in one subscription. Mimecast Spam Filter mitigates the risk without the high price tag usually associated with email management solutions. Mimecast’s spam filter stops 99% of spam with 0.0001% false positives, contains 100% viruses and malware, including zero-hour protection, and minimizes disruption by protecting against attacks.

Mimecast product reviews confirm this service’s efficiency, arguing that it maintains their inboxes clean and safe, and they don’t have to worry about unsolicited emails piling up. Not allowing spam emails to go through is the most significant benefit users have seen from Mimecast. 


Mailbox Continuity Review

Mailbox Continuity makes sure that company employees have access to their emails and attachments on any device. As a company admin, you can monitor all emails (inbound and outbound) and manage email administration tasks via the continuity Mimecast portal. Hence, you keep the communications flowing after an email server outage. 

Having read multiple Mimecast reviews, we discovered that clients like that the service can be used manually and automatically. Additionally, it seamlessly connects to most mailboxes and allows document retrievement from the archive in seconds. 

As far as the negative reviews are concerned, people said that it takes a while to search for things, and they would also like it if the program is more intuitive and the notices are more precise as to why the event is being triggered. 


Mimecast Web Security Review

Mimecast monitors web activity at the DNS layer to block inappropriate behavior and stop accidental access to sites containing threatening content. With Mimecast, you get robust email security control that protects clicks from email messages, social media, personal webmail, and instant messaging. Beyond securing office-based employees, the service protects remote and mobile workers too, regardless of their location or device. 


Proactive Protection

According to Mimecast reviews, users love the software’s proactive protection by blocking sites of phishing attacks or delivering malware, inspecting content and file downloads using a dynamic proxy, restrain compromised devices, and identifying threats using multi-source intelligence. This type of defense allows you to stop threats before they reach your network, providing more advanced protection than traditional defenses like endpoint protection and firewalls. 


Acceptable Web Use Policies

With Mimecast, you can easily set up acceptable web use policies to mitigate legal, compliance, and security risks. Users appreciate the granularity you can apply policies for different email types to make sure policies meet specific requirements or apply policies to specific users, ground ups, networks.

You can see who uses which apps and how often, monitor, block, and selectively manage apps, and enforce consistent control and protection. As with the apps, Mimecast allows you to track which employee is visiting what sites through simple visualization of key metrics.

Cloud Archive allows you to maintain compliance and recover lost data. It’s SEC 17a-4 validated with tamper-resistant chains of custody. It provides a fully-indexed cloud information archive, unified management, compliance maintenance, self-service e-discovery, and easy legacy data archive transfer.

Also, they like that you can avoid the necessity to have to delete email to have them in the cloud. 

One potential downside is that the platform’s multiple features can make it challenging to determine how to perform specific actions. It might also take time to get used to navigating the layout, and users would like to see the search interface improved and made more intuitive.


Mimecast Secure Messaging Review
