🔐 𝐑𝐞𝐬𝐢𝐥𝐢𝐞𝐧𝐜𝐞, 𝐆𝐫𝐨𝐰𝐭𝐡, 𝐚𝐧𝐝 𝐚 𝐂𝐥𝐞𝐚𝐫 𝐕𝐢𝐬𝐢𝐨𝐧 𝐟𝐨𝐫 𝐭𝐡𝐞 𝐅𝐮𝐭𝐮𝐫𝐞

Two years ago, I stepped away from #CapNetSols 𝐂𝐚𝐩𝐢𝐭𝐚𝐥 𝐍𝐞𝐭𝐰𝐨𝐫𝐤 𝐒𝐨𝐥𝐮𝐭𝐢𝐨𝐧𝐬 𝐋𝐢𝐦𝐢𝐭𝐞𝐝 “Capital Networks” to support a close family member through their final months. Since then, once a leading light in Welsh cybersecurity; 𝐂𝐍𝐒 𝐬𝐚𝐝𝐥𝐲 𝐜𝐥𝐨𝐬𝐞𝐝 𝐢𝐭𝐬 𝐝𝐨𝐨𝐫𝐬.

But every cloud has a silver lining.

Now well into our second year of integrating CNS’ cyber team into Pentest Cyber, we’re proud to be on track to surpass CNS’ most successful year ever. We've upskilled our team, introduced carefully selected new products, and laid out a bold 10-year roadmap.

🏴 We now stand as 𝐨𝐧𝐞 𝐨𝐟 𝐭𝐡𝐞 𝐟𝐞𝐰 𝐩𝐫𝐢𝐯𝐚𝐭𝐞𝐥𝐲-𝐨𝐰𝐧𝐞𝐝 𝐜𝐲𝐛𝐞𝐫𝐬𝐞𝐜𝐮𝐫𝐢𝐭𝐲 𝐟𝐢𝐫𝐦𝐬 𝐢𝐧 𝐖𝐚𝐥𝐞𝐬, surrounded by VC-funded “ex-Welsh” companies that often rely on aggressive sales and upselling tactics. We’re different - and proudly so.

To our incredible, loyal portfolio of CE/+ and Pentest clients: 𝐭𝐡𝐚𝐧𝐤 𝐲𝐨𝐮. And to those considering a change: 𝐧𝐞𝐰𝐜𝐨𝐦𝐞𝐫𝐬 𝐚𝐫𝐞 𝐚𝐥𝐰𝐚𝐲𝐬 𝐰𝐞𝐥𝐜𝐨𝐦𝐞.

We remain committed to our founding ethos: 🌍 𝐖𝐨𝐫𝐥𝐝-𝐂𝐥𝐚𝐬𝐬 𝐐𝐮𝐚𝐥𝐢𝐭𝐲 𝐚𝐭 𝐖𝐞𝐥𝐬𝐡 𝐏𝐫𝐢𝐜𝐞𝐬.

If you're feeling the pressure of VC-driven “rush-to-exit” strategies, maybe it’s time to explore a more stable, long-term partnership.

📈 𝐏𝐞𝐧𝐭𝐞𝐬𝐭 𝐂𝐲𝐛𝐞𝐫 𝐦𝐢𝐠𝐡𝐭 𝐣𝐮𝐬𝐭 𝐛𝐞 𝐭𝐡𝐞 𝐬𝐦𝐚𝐫𝐭𝐞𝐬𝐭 𝐢𝐧𝐯𝐞𝐬𝐭𝐦𝐞𝐧𝐭 𝐲𝐨𝐮 𝐦𝐚𝐤𝐞 𝐢𝐧 𝐭𝐨𝐝𝐚𝐲’𝐬 𝐮𝐧𝐜𝐞𝐫𝐭𝐚𝐢𝐧 𝐥𝐚𝐧𝐝𝐬𝐜𝐚𝐩𝐞.

🔐 Do your IT providers mark their own homework?:
Why People Partner PTC 🎯 👏 for Cyber Essentials & Pentests 🔍

Independence and expertise are critical to building trust.

Deep experience means we understand what NCSC and their Cyber Essentials partner are looking for and how to raise REAL defences that work.

Since the launch of Cyber Essentials our staff have thousands of successes including niche knowledge of the largest global enterprises.

Strategic advantages:

✅ Avoid Conflicts of Interest
When MSPs assess or test their own clients, it can compromise objectivity. Ensure transparency, credibility, and trust with independent assessments.
Essential for compliance, insurance, and client confidence.
✅ Elite-Level Testing & Assurance
We use professional-grade tools and deploy OSWE-level penetration testers, all vetted to a high UK government standard. This ensures your testing is thorough, accurate, and aligned with the highest security standards.
✅ Trusted Across Sectors
From finance and healthcare to education, manufacturing, and government, we’ve helped thousands of organisations achieve Cyber Essentials certification and improve their security posture.
✅ Collaborative Approach with MSPs
We work alongside MSPs NOT to compete BUT to enhance services. We strengthen offerings to help your clients meet obligations with confidence.
✅ Compliance Made Simple
We streamline Cyber Essentials and penetration testing with NO HIDDEN EXTRAS, to help clients meet requirements stress-free/minimal disruption.

If you're an MSP or a business looking to strengthen your cyber posture, let’s talk. Together, we can raise the bar for cyber resilience.
