How much does cyber security cost for a small business?
Cyber security is built into our Core Secure managed IT plan at £89 per user per month (excluding VAT), which adds continuous vulnerability monitoring, a security baseline, Cyber Essentials-aligned controls and monthly security reporting on top of full IT support. Cyber Essentials certification starts from the £320 + VAT IASME fee, with readiness help quoted separately. See Managed IT plans and Cyber Essentials pricing.
What is the difference between Cyber Essentials and IASME Cyber Assurance?
Cyber Essentials covers five technical controls, such as firewalls, updates and access control. IASME Cyber Assurance is broader: it also covers governance, risk assessment, incident response, training and data protection (UK GDPR). Level 1 is a verified self-assessment and Level 2 includes an independent audit. ABCOM holds IASME Level 2 and can guide you through either standard.
What should we do if we have a cyber attack?
Phone us straight away on 01444 871 200. Don’t switch devices off or pay any ransom. We will contain the threat, for example by locking accounts and isolating devices, then investigate and restore from backup. Report the incident to Action Fraud, and if personal data is affected you may need to report it to the ICO within 72 hours.
Do you provide cyber security for businesses and charities in Sussex?
Yes. ABCOM is based in Burgess Hill and protects businesses and charities across Sussex and the UK, with remote monitoring and onsite support where needed.
What is the difference between a penetration test and a vulnerability assessment?
A vulnerability assessment uses automated scanning to find known weaknesses, such as missing patches or misconfigured services, across your systems. A penetration test goes further: a qualified tester actively tries to exploit weaknesses, as a real attacker would, to show what could actually be accessed. Most organisations benefit from regular vulnerability scanning plus a periodic penetration test.
What does Microsoft 365 security hardening involve?
We review and tighten your Microsoft 365 tenant: enforcing multi-factor authentication and Conditional Access, blocking legacy sign-in, tightening admin roles, configuring Defender for Office 365 against phishing and malware, and improving your Microsoft Secure Score. It is one of the most effective ways to prevent email account takeover.
What is Microsoft Purview and do we need it?
Microsoft Purview is Microsoft’s set of data governance and compliance tools, including sensitivity labels, data loss prevention, retention policies and Compliance Manager. It helps you find, classify and protect sensitive information, which supports UK GDPR. If you hold personal or confidential data, our managed Purview service sets it up and keeps it working for you.
Is your support available 24/7?
Our service desk has a 2-hour response SLA during business hours (8am to 6pm, Monday to Friday). Our endpoint detection and response (EDR) software runs 24/7 on every protected device, and it is monitored around the clock by a security operations centre (SOC).
What do EDR, SOC, NOC and ITDR mean?
EDR (endpoint detection and response) is security software on each laptop, desktop and server that watches for signs of an attack and can isolate an infected device. A SOC (security operations centre) is the team of analysts who investigate those alerts around the clock. A NOC (network operations centre) monitors the health and availability of networks, servers and devices, so it keeps systems running rather than hunting attackers. ITDR (identity threat detection and response) is the identity side of the same idea: it looks for signs that a Microsoft 365 account has been taken over, such as logins from unusual places or suspicious mailbox rules. Microsoft includes identity protection features in its premium plans.
