Dimensions summary
This listing offers one pricing option: a bundle of 100 Advanced Email Security users billed as a yearly contract. You pay per bundle for a one-year term, so costs scale by adding bundles as your user count grows. The listed bundle covers up to 100 users. If you need coverage above 100 users, want custom plans, or prefer a 3-year term, you contact the vendor for a quote. Pricing is quantity-based around the 100-user unit rather than tiered by feature level.
Top-of-mind questions for buyers
A user is an individual email account protected by the service. The bundle covers up to 100 such accounts for the year. If your organization has more than 100 email users, you contact the vendor to arrange coverage above that count.
The listed bundle covers up to 100 users as a single unit. To cover more than 100 users, you do not add partial bundles here. Instead, you contact the vendor for custom pricing and plans above 100 users.
The service defends against phishing, business email compromise, ransomware, and malware using AI-driven detection. You can deploy through a secure gateway that routes incoming mail, or through an API that layers protection into your cloud email platform. Both options are offered.

Strong Threat Protection, but Slow Links and False Positives Frustrate
Reviewed on Nov 03, 2026
Review provided by G2
What do you like best about the product?
I like Mimecast Advanced Email Security’s real-time, time-of-click protection and impersonation detection. It rewrites and scans URLs instead of only scanning them in emails, which helps protect against malware and phishing attempts. It does a solid job protecting our inboxes and links, and the setup was easy and smooth.
What do you dislike about the product?
I hate the delay. URL redirects feel sluggish most of the time, especially on my company iPhone, where it takes forever to load. It disrupts me when I’m on the go, and copying links in Safari is frustrating because I have to view them in the Microsoft browser. False positives are also annoying: real emails end up in the quarantine box and I have to release them. I actually missed a vendor email because of this.
What problems is the product solving and how is that benefiting you?
I use Mimecast Advanced Email Security to protect our inboxes and Teams links from malware and phishing, mask links and check they’re safe through its servers, and prevent email downtime.

Powerful Threat Protection, but Requires Careful Fine-Tuning
Reviewed on Oct 30, 2026
Review provided by G2
What do you like best about the product?
I like Mimecast Advanced Email Security’s targeted threat protection, especially URL Protect’s real-time URL rewriting and click-time analysis, and Attachment Protect’s sandboxing and file analysis to block malicious links, credential-harvesting attempts, zero-day malware, and ransomware. I also value its impersonation protection, policy controls, and tools for journaling, archiving, e-discovery, and investigating reported phishing emails. The logs and dashboard help me trace delivery status and address issues. The initial setup was relatively straightforward, and the onboarding documentation and guided setup made it manageable. URL protection, attachment sandboxing, and impersonation defense give me confidence in stopping advanced phishing and day-to-day threats.
What do you dislike about the product?
I find URL Protect and Attachment Protect can be overly aggressive, blocking legitimate business links or delaying time-sensitive file deliveries. I have to keep fine-tuning bypass policies and help users handle blocked items without compromising security. The admin console has a steep learning curve, and managing overlapping policies and definitions across multiple domains can get complex and feel counterintuitive. URL rewriting can occasionally break specific web app integrations, and Mimecast warning pages on safe links can confuse users. Digging into older logs or exporting them to tools like Splunk or Microsoft Sentinel can also feel clunky compared with using those platforms directly.
What problems is the product solving and how is that benefiting you?
Mimecast Advanced Email Security solves severe email threats like spear phishing, BEC, zero-day malware, and credential harvesting by using AI-driven threat intelligence, real-time URL rewriting, and deep attachment sandboxing. For our IT and security operations, this delivers massive value by stopping attacks before they hit user inboxes, eliminating alert fatigue, protecting our corporate cloud environment, and ensuring business continuity even during outages. Ultimately, it frees up our engineering team from manual ticket firefighting and secures our primary enterprise attack vector.

Mimecast Advanced Email Security: Powerful Threat Protection and Centralized Visibility
Reviewed on Oct 30, 2026
Review provided by G2
What do you like best about the product?
What I like most about Mimecast Advanced Email Security is its ability to protect organizations against phishing, malware, spam, and other email-based cyber threats. Its advanced threat detection, URL and attachment protection, and real-time security monitoring help reduce risks and improve overall email security. The centralized management and visibility also make it easier for security teams to identify and respond to suspicious activities.
What do you dislike about the product?
One area that could be improved is the user interface, as some advanced settings and configurations may take time for new users to understand. Additionally, occasional false positives may require manual review, and managing security policies can involve an initial learning curve. Overall, improving ease of use and simplifying configuration would make the product even better.
What problems is the product solving and how is that benefiting you?
Mimecast Advanced Email Security helps address key business risks such as phishing, business email compromise, malware, ransomware, and malicious attachments. It improves protection against email-based cyberattacks, reduces the risk of data breaches and financial fraud, and helps employees communicate more securely. This benefits the organization by strengthening its security posture, reducing manual security efforts, and improving overall business continuity.

Powerful Granular Controls, but a Steep Learning Curve in the Admin Portal
Reviewed on Oct 29, 2026
Review provided by G2
What do you like best about the product?
I appreciate that Mimecast Advanced Email Security can be very granular to suit different environments. It gives administrators precise control over email policies, allowing us to configure custom routing, create specific bypasses, and adjust threat protection levels based on our organization's unique requirements without disrupting legitimate mail flow.
What do you dislike about the product?
While the high level of granularity is a major plus, it also means the administrative portal can be quite complex and overwhelming for new users. There is a relatively steep learning curve to understand exactly where all the different policies, definitions, and settings are located, which can make the initial setup and routine troubleshooting more time-consuming than necessary.
What problems is the product solving and how is that benefiting you?
Mimecast solves the persistent problem of sophisticated phishing attacks and malicious attachments reaching our end users. By reliably filtering out these threats before they hit the inbox, it significantly reduces our organization's cyber risk profile.

Powerful Threat Protection, Though Policies Need Fine-Tuning
Reviewed on Oct 28, 2026
Review provided by G2
What do you like best about the product?
I use Mimecast Advanced Email Security as our primary secure email gateway to protect our Microsoft 365 environment. Its targeted threat protection works exceptionally well against sophisticated phishing, domain spoofing, and zero-day malware before emails reach user inboxes. Real-time scanning and safe file conversions give our team peace of mind by defanging malicious links and weaponized files in transit. It reliably catches subtle executive impersonation that standard filters often miss. URL rewriting checks destination links when an employee clicks, helping prevent post-delivery web attacks, and safe file conversion blocks malicious files, weaponized PDFs, and macros before they reach user devices with minimal workflow interruption. Its core protection capabilities and threat visibility are top-notch.
What do you dislike about the product?
I find Mimecast Advanced Email Security could be easier to configure and manage, especially for teams handling a large volume of emails. The reporting could be clearer and policy settings more straightforward, and I’d like fewer false positives. When legitimate business emails are flagged, administrators have to review quarantine messages, verify they’re safe, and release them, which creates extra work and can delay business communication. Setting up and fine-tuning policies also takes time, and clearer documentation and better-organized configuration options would help.
What problems is the product solving and how is that benefiting you?
I use Mimecast Advanced Email Security to stop sophisticated impersonation attempts and zero-day attachments before they reach our users’ inboxes.
