How we protect Merthyr Tydfil businesses (Merthyr Tydfil Industrial Park, Pentrebach, Goat Mill Road, Dowlais, Aberdare and the A465 Heads of the Valleys corridor)
- Monthly Cyber Posture (£395 + VAT/month · Annual Plan — Main Product): 4 hours every month of dedicated security engineering to get your security posture into tip-top shape and keep it there, plus continuous Microsoft 365 & DMARC drift monitoring, a quarterly executive & cyber-insurance report, and your annual guided Cyber Essentials readiness included (you only pay the IASME body fee).
- Guided Cyber Essentials & Cyber Essentials Plus (CE+): Ideal for Merthyr Tydfil firms bidding on Merthyr Tydfil County Borough Council, Welsh Government infrastructure contracts and housing/construction tenders. One-off guided CE readiness starts from £295 + VAT (+ IASME fee); Cyber Essentials Plus (CE+) with hands-on vulnerability verification is quoted per company.
- Microsoft 365 security hardening: Conditional Access policies, phishing-resistant MFA, admin account separation, external mail-forwarding locks, SharePoint permission cleanup and 28-point tenant reviews.
- DMARC, SPF & DKIM email security (£295 + VAT fixed price): Stop criminals sending fake invoices or bank-detail changes pretending to be your Merthyr Tydfil domain.
Whether your Merthyr Tydfil team has 5 staff or 150, we check 28 critical controls across sign-ins, global admins, email spoofing, SharePoint, Copilot exposure, backups and devices—and send you a Red, Amber and Green PDF report within 24 hours.

Frequently asked questions — Merthyr Tydfil
How does the Free 28-Point Microsoft 365 Security Audit work for Merthyr Tydfil firms?
It is completed 100% remotely in a 15-minute read-only screen-share with Ross Owen (or via temporary Global Reader access). Nothing in your Merthyr Tydfil Microsoft 365 tenant is changed during the audit. Within 24 hours you receive a Red, Amber and Green PDF report showing where your sign-ins, admin accounts, email forwarding, SharePoint permissions and backups stand.
What is included in the £395 + VAT/month Monthly Cyber Posture plan?
Monthly Cyber Posture is our flagship annual plan for Merthyr Tydfil SMEs and professional practices. It gives you 4 hours every month of dedicated security engineering to remediate gaps and harden your systems, continuous Microsoft 365 and DMARC drift monitoring, a quarterly executive & cyber-insurance posture report, and your annual guided Cyber Essentials readiness preparation included (you only pay the IASME body fee).
Do you offer both Cyber Essentials and Cyber Essentials Plus (CE+) in Merthyr Tydfil?
Yes. We provide one-off guided Cyber Essentials certification from £295 + VAT (plus the mandatory IASME certification fee, priced by staff size), and we deliver Cyber Essentials Plus (CE+)—which includes the independent hands-on technical vulnerability audit—on a quote-per-company basis depending on your user count, device types and locations.
Can you work alongside our existing Merthyr Tydfil IT support provider?
Yes. You do not need to switch IT provider. Most of our Merthyr Tydfil clients keep their existing day-to-day IT support or internal IT manager and use AlphaSec specifically for independent Microsoft 365 audits, DMARC enforcement, Cyber Essentials / CE+ certification and ongoing security posture oversight.
