ModernCyber Risks For Businesses
The real risks facing modern UK
businesses and how to reduce them
Cyber risk has changed.
Most breaches now start with everyday systems.
Modern cyber risk is rarely about one dramatic attack. For most businesses, it starts with the tools your team uses every day, Microsoft 365, email, passwords, devices, remote access and backups.
ATS helps businesses reduce these risks calmly and methodically, strengthening the areas attackers most commonly exploit before they become business-critical incidents. We deliver cyber security to businesses across West Sussex, including IT support in Chichester.
Practical cyber security is not about creating fear.
It is about bringing the most important risks under control before they become operational incidents.
Where Risks Usually Start
- Identity & access – Weak MFA, shared logins, unused accounts and excessive admin permissions.
- Microsoft 365 – Legacy authentication, risky sharing settings and over-permissioned mailboxes.
- Email – Phishing, invoice fraud, impersonation and account compromise.
- Devices – Unmanaged laptops, unpatched machines and personal devices used for work.
- Recovery – Untested backups, unclear restore processes and weak ransomware recovery planning.
- Remote work – Home networks, unmanaged access and inconsistent device security.
MICROSOFT 365 SECURITY

Original Risks
- Inconsistent MFA across staff & admins
- Legacy authentication still enabled
- No independent Microsoft 365 backup
- Limited visibility of endpoint security
What ATS Implemented
- Phishing-resistant MFA & Conditional Access
- Hardened tenant & legacy auth disabled

FAQ
Cyber security questions UK businesses ask us most
Most modern UK businesses need a layered, managed cyber security service rather than a single product. At minimum that means phishing-resistant MFA on every account, Conditional Access, managed endpoint protection (EDR), advanced email defence, patch management, independent Microsoft 365 backup, continuous monitoring and a documented incident response plan. ATS delivers this as one accountable service rather than a stack of disconnected tools.
Start with the basics done properly: enforce phishing-resistant MFA everywhere (including admins and shared mailboxes), disable legacy authentication, apply Conditional Access policies, tighten SharePoint and OneDrive sharing, enable advanced email defence, and put independent backup in place beyond Microsoft’s native retention. Then layer on continuous monitoring of identity risk and tenant configuration drift. ATS can benchmark your current posture and deliver this as a managed service.
Multi-factor authentication (MFA) requires something more than a password to sign in, typically an approval on a trusted device or a hardware key. It is the single most effective control against account takeover, blocking the vast majority of automated and opportunistic attacks. Modern, phishing-resistant MFA also defends against advanced techniques like real-time phishing proxies and token theft, which traditional SMS codes do not.
Ransomware risk is reduced through layered controls: hardened identities (MFA, Conditional Access), managed EDR with active response, continuous patching, restricted local administrator rights, segmented backups that ransomware cannot reach, and a tested recovery plan. Just as importantly, monitoring and incident response capability so an early intrusion is caught and contained, before encryption and data extortion occur.
Look for an established UK provider with operational maturity, named engineers, documented processes, change control, incident response capability and recognised certifications such as Cyber Essentials and Microsoft Partner status. Avoid fear-led sales, single-product vendors and providers who treat security as an upsell. The right partner will deliver layered protection, strategic guidance and rapid response as one ongoing service.
Our average response time is under 11 minutes, with a target of under 30 minutes across all support channels. Suspected security incidents, including account compromise, phishing reports, malware detections and unusual sign-in activity, are escalated immediately under documented major-incident procedures. 98% of routine issues are resolved on first contact by our UK-based engineers.
