Mimecast Partner UK organisations trust for email security, resilience and human risk reduction.

Mimecast is a top tier in the Mimecast Partner Programme that reflects demonstrated UK delivery across email security, resilience, archiving and user awareness. Transputec holds Premier, which means UK customers get priority access to Mimecast roadmap and beta programmes, faster Mimecast escalation, certified Mimecast architects on call, and a single accountability line for design, deployment and run. See Mimecast’s official UK partner programme page and our cyber security pillar for how email security fits.

The full Mimecast stack: Email Security 360 (URL Protect, Attachment Protect, impersonation defence, internal-email protection), Brand Exploit Protect, Domain-based Message Authentication, Reporting and Conformance (DMARC) Analyzer, Cloud Archive for compliant retention and eDiscovery, Mailbox Continuity, Content Examination for Data Loss Prevention (DLP), Awareness Training and Human Risk Management. We design the deployment, integrate it with your UK service desk and Security Operations Centre (SOC), and run it as a managed service if you want us to.

Both protect email, but they sit in different places in the stack. Microsoft Defender for Office 365 is built into your Microsoft 365 tenant and catches well-known phishing, malware and spam at the mailbox layer. Mimecast sits upstream of Microsoft 365 as a secure email gateway, adding deeper impersonation defence, brand exploit protection, DMARC enforcement, mailbox continuity if Microsoft 365 has an outage, and compliant 10-year cloud archive. Most UK enterprises run them together: Mimecast for outer-layer threat blocking and continuity, Defender for inner-layer mailbox protection. See our Microsoft Modern Workplace pillar for context.

Mimecast is sold per-mailbox per-month, with the price varying by which bundle you choose. As an indicative UK figure, the Email Security 360 Plus bundle (URL Protect, Attachment Protect, impersonation defence, awareness training) typically starts from around £6 per user per month at SME volumes, dropping for larger seat counts. Cloud Archive and Mailbox Continuity are extras priced separately. We share an indicative UK quote against your exact seat count in our 30 minute call. For UK cyber-spend benchmarks see our blog on cybersecurity for UK SMEs.

Yes. We migrate UK customers from Proofpoint, Barracuda, Avanan, Microsoft Defender for Office 365 standalone and other legacy email security platforms onto Mimecast. The approach is the same each time: discovery, parallel-run with policy tuning, cut-over with rollback plan, then handover to either your team or our managed service. Mimecast typically lands as part of a broader UK cyber security programme rather than a single tool swap.

Yes. Mimecast Awareness Training and Human Risk Management is a core part of every email security engagement we run in the UK. Each user gets a risk score based on actual behaviour (clicks, reports, reused credentials, simulation results); training is then targeted to where each user needs it, not a generic annual quiz. Exec dashboards show whether behaviour is changing month on month. Aligns to NCSC guidance, see the NCSC phishing guidance we factor into the programme design.

Yes. Transputec is ISO 27001 certified for information security management and Cyber Essentials Plus accredited, so every Mimecast engagement we run, from initial policy design to ongoing run, passes through controls that satisfy UK GDPR and the Information Commissioner’s Office (ICO). All Mimecast operations are delivered from UK staff in our London headquarters. Read the ISO 27001 standard and see our full UK certifications list.

Yes. Mimecast feeds into our managed SOC for round-the-clock email-borne threat monitoring, with response playbooks for Business Email Compromise (BEC), credential phishing and ransomware delivery attempts. User-reported phishing flows into the SOC queue; our UK service desk wraps round Mimecast support escalation and Mimecast-side ticket management so your team has one number to call. See our managed SOC service for the wider picture.
