What is EDR (Endpoint Detection and Response)?

EDR is a cybersecurity solution that continuously monitors and collects data from devices across your network to detect and respond to threats in real-time. It provides visibility into suspicious activities and enables automated or manual threat response without waiting for traditional antivirus updates.

What is MDR (Managed Detection and Response)?

MDR combines EDR tools with expert security analysts who monitor your systems 24/7, investigate alerts, and respond to threats on your behalf. It's a fully managed security service that removes the burden of threat detection from your IT team.

What is XDR (Extended Detection and Response)?

XDR extends threat detection beyond endpoints to cover networks, servers, email, and cloud systems, giving you a unified view of your entire security posture. It correlates data across all these sources to identify sophisticated, multi-stage attacks.

What is SIEM (Security Information and Event Management)?

SIEM is a platform that collects, analyses, and correlates security logs and events from across your entire IT environment to detect suspicious patterns and potential attacks. It centralises security data and helps you understand what's happening across your infrastructure.

What is SOC (Security Operations Centre)?

A SOC is a team of security experts who monitor your systems 24/7, respond to incidents, and manage your overall security programme. It can be in-house, outsourced to an MSP, or a hybrid model.

Zero Trust is a security philosophy that assumes no user or device is trustworthy by default. Every access request requires verification through authentication, authorisation, and encryption.

What is MFA (Multi-Factor Authentication)?

MFA requires users to verify their identity using two or more methods, such as a password, a one-time code, or biometric data. Even if a password is stolen, an attacker cannot access the account without the additional factor.

Phishing is a social engineering attack where criminals send deceptive emails or messages to trick users into revealing sensitive information or downloading malware. These attacks often impersonate trusted organisations.

Ransomware is malicious software that encrypts your files and systems, making them inaccessible until you pay a ransom to the attacker. Even paying offers no guarantee of recovery.

What is Threat Intelligence?

Threat Intelligence is data and analysis about known and emerging cybersecurity threats, including attacker tactics, vulnerable systems, and indicators of compromise. It helps organisations stay ahead of evolving threats.
