Cyber Security

Protecting your people, data and network from evolving threats

Winstel Technologies offers a layered approach to cybersecurity, helping businesses stay protected in an evolving digital threat landscape. Through partnerships with leading security providers, we deliver solutions that secure your systems, data, and users - whether they're working in-office or remotely.

Email Authentication & Domain Protection (Sendmarc)

Sendmarc protects your domain against spoofing and impersonation attacks by enforcing DMARC, SPF and DKIM protocols. This helps maintain your brand’s email trust and prevents cybercriminals from exploiting your identity.

Email Security (Mimecast)

We partner with Mimecast to provide advanced email protection, ensuring your business is safeguarded against spam, phishing, malware and targeted attacks. Mimecast’s threat intelligence and continuity tools help reduce risk and improve resilience.

Network Security (Sophos Firewalls)

With Sophos next-generation firewalls, we deliver robust network protection that detects and blocks threats in real time. Features include deep packet inspection, web filtering, intrusion prevention and secure remote access.

Phishing Simulation & Awareness Training

We offer phishing testing and employee training tools that simulate real-world attacks, helping your team recognise and respond to threats before they cause damage. This strengthens your human firewall and supports ongoing compliance efforts.
