Companies that use Mimecast

Source: Analysis of 100 job postings that mention Mimecast

I noticed that Mimecast purchasing decisions sit primarily with IT and security leadership, with Directors of Information Technology (14%) and Directors of Information Security (13%) leading the charge. These buyers are focused on comprehensive email security and compliance, often managing hybrid environments alongside Microsoft 365, Exchange, and cloud platforms. They're hiring for roles that balance strategic oversight with hands-on technical expertise, suggesting Mimecast is a critical enterprise tool requiring dedicated management.

Day-to-day users span from IT Support Specialists (11%) and System Administrators (10%) to specialized Security Operations and Email Security Engineers. These practitioners handle message tracing, policy management, threat investigation, and phishing response. They work extensively with mail routing, DLP policies, and integration with broader security stacks including SIEM platforms, endpoint protection, and identity management tools. The hands-on nature of these roles shows Mimecast requires active administration rather than set-it-and-forget-it deployment.

The key pain points center on threat prevention and operational efficiency. Companies explicitly seek to "protect against phishing, malware, and other email-borne threats" and "ensure data security and compliance." Multiple postings mention "monitor and respond to security alert notifications" and "investigate and troubleshoot issues" related to email security. Organizations are building security-first cultures where email gateway management is mission-critical, with one posting noting the need to "minimize risk" while another emphasizes "proactive measures to mitigate risks" in an evolving threat landscape.

I noticed that Mimecast customers span an impressive range of industries, but they share a common thread: they're service providers and relationship-driven businesses. These aren't companies selling widgets off a shelf. They're healthcare providers caring for patients, financial advisors managing wealth, construction firms delivering projects, government agencies serving communities, and professional services firms acting as trusted advisors. Many describe themselves as partners rather than vendors, emphasizing long-term relationships over transactions.

Most of these organizations sit firmly in the mature, established category. The employee counts cluster between 11-200, with many reporting 50-200 employees. Several mention decades of operation, like the accounting firm with "origins over 50 years ago" or the credit union "founded in 1951." Very few show venture funding, and those that do are typically at modest levels. These are profitable, sustainable businesses that have found their market fit and are focused on steady operations rather than explosive growth.

I noticed that Mimecast users show a clear pattern of being security-conscious, growth-stage B2B companies with hybrid work models and strong digital presences. The combination of Intune, KnowBe4, and Mimecast itself reveals organizations that take enterprise security seriously and are willing to invest in multiple layers of protection. These aren't startups operating lean, they're companies mature enough to understand that email security, endpoint management, and security training form a critical defense triad.

The pairing of Mimecast with KnowBe4 is particularly revealing. Companies using both recognize that security isn't just about technology, it's about people. They're addressing phishing threats from two angles: Mimecast filters malicious emails while KnowBe4 trains employees to spot what gets through. The strong presence of Intune alongside these tools tells me these companies manage distributed workforces with BYOD or remote work policies, needing centralized control over devices accessing corporate email. The Zoom Business correlation reinforces this, these are organizations that embraced remote collaboration and needed enterprise-grade communication tools to match their security posture.

The full stack suggests these are sales-led and marketing-led B2B companies in growth mode. DocuSign's presence indicates significant contract volume and sales velocity. The combination of Google Search Console and Yoast points to companies investing in inbound marketing and SEO, trying to generate leads organically rather than relying solely on outbound sales. They're sophisticated enough to track and optimize their digital presence, which requires dedicated marketing resources.
