Cyber Security in Newcastle
Layered protection for your people, your data and your reputation.
Newcastle's legal, financial and healthcare sectors handle sensitive client data every day, making them prime targets for ransomware, phishing and business email compromise. Peritus Digital brings enterprise-grade cyber security to Newcastle businesses of all sizes: email protection, penetration testing, managed detection and response, and Essential Eight compliance support. We are local, which means threat response does not wait for a call centre queue.
01 — Scope
What's included — Cyber Security for Newcastle businesses
Email security
Advanced threat protection, business email compromise detection and SPF/DKIM/DMARC configuration. Email is the number one attack vector — we close that door.
Web & DNS filtering
A preventive layer that blocks malicious, phishing and newly-registered domains at the DNS level — before a connection is ever made. It stops drive-by malware and risky downloads, severs command-and-control callbacks if a device is compromised, and enforces acceptable use — on your network and for staff working remotely.
Security awareness training
Realistic phishing simulations and role-based training that turn your team from a vulnerability into a last line of defence.
Penetration testing
Independent assessment of your network, applications and endpoints — we find the gaps before attackers do.
Managed detection and response
24/7 threat monitoring with expert-led investigation and response. Threats are contained fast, not just logged.
Vulnerability management
Continuous scanning, prioritised remediation and clear reporting — so your risk posture keeps improving, not just getting audited.
Compliance support
Practical guidance on Essential Eight, ISO 27001 and industry-specific frameworks. Compliance that actually reduces risk.

03 — Questions
Cyber Security in Newcastle — common questions
01Are Newcastle businesses targeted by cyber attacks?
Yes — Newcastle's legal, financial, construction and healthcare sectors are actively targeted. Ransomware gangs and phishing campaigns don't discriminate by geography; they target any business with weak defences. Local firms often have less mature security than large metro companies, making them attractive.
02What does Essential Eight compliance mean for a Newcastle business?
The Essential Eight is the ACSC's baseline cybersecurity framework. For Newcastle businesses, implementing it at Maturity Level 1 or 2 closes the most exploited attack paths, often satisfies cyber insurance requirements and demonstrates due diligence to enterprise clients and government contracts.
03How long does a penetration test take for a Newcastle SMB?
A focused external pen test for a typical Newcastle SMB typically takes 3–5 business days from scoping to final report. Internal network and application tests vary by scope. We provide a practical remediation roadmap alongside the findings.
04Can you help after a cyber incident, not just before one?
Yes — we provide incident response for Newcastle businesses including containment, forensic investigation, regulatory notification guidance and post-incident hardening. If you suspect a breach, call us immediately rather than waiting.
