How does multi-factor authentication work?

Multi-factor authentication (MFA) adds vital layers of protection by requiring users to verify their identity with more than just a password. By combining factors such as something you know, something you have, and something you are, MFA makes it significantly harder for attackers to gain unauthorised access. From SMS codes and authenticator apps to biometrics and hardware tokens, MFA reduces the risk of account compromise by over 99.9% when properly implemented, making it an essential defence in today’s cyber threat landscape.

Managed IT Support: Can you trust your provider?

Outsourcing IT to a managed service provider (MSP) means entrusting them with your data, systems, and business continuity. But can you truly trust your provider? Recent breaches at Jaguar Land Rover and Marks & Spencer highlight how vulnerabilities within MSPs can disrupt entire organisations.

Trust depends on transparency, accountability, and compliance with recognised standards like ISO 27001 or the ScotlandIS ITMSP Best Practice Charter.

At Net-Defence, we prioritise security, proactive monitoring, and tailored support. Our commitment to best practice ensures clients’ systems remain protected, compliant, and resilient.

If you’re unsure whether your current MSP meets these standards, now is the time to re-evaluate who you trust with your IT infrastructure.
