Email Security

Email Security

Email remains the most common attack vector for businesses, used to deliver phishing scams, ransomware, and account compromise. Without the right protection, just one wrong click can expose your organisation to serious risk. Arc’s email security services help stop threats before they reach the inbox. Using intelligent filtering, domain protection, and threat detection, we secure both cloud and on-premise email environments while keeping your communication flowing.

What we protect against

Phishing Attacks – Stop deceptive emails designed to trick users into revealing passwords, financial details or sensitive data.

Malware & Ransomware – Block attachments and links that deliver viruses, trojans, or ransomware payloads.

Spoofing & Impersonation – Detect and block attempts to impersonate internal staff, vendors, or leadership.

Business Email Compromise (BEC) – Identify signs of account hijacking or fraud targeting finance and HR departments.

Spam & Bulk Mail – Keep mailboxes clean by filtering non-malicious, low-value traffic.
