Cyber Security

The reality

Cyber attacks aren’t something that happens to other people. They’re happening right now — to businesses exactly like yours, in suburbs exactly like yours. A single phishing email can cost a small business tens of thousands of dollars. A ransomware attack can shut down operations for weeks. And the reputational damage? That can last years.

The difference between the businesses that recover and the ones that don’t usually comes down to one thing: preparation.

At Peritus Digital, we take a layered approach to cybersecurity. That means we don’t just install an antivirus and walk away. We build defence in depth — from your people and their habits, through your email and endpoints, all the way to your network perimeter and beyond. Because no single product stops every threat. But a well-designed security posture does.

What we cover

Email security and protection

Email remains the number one attack vector for Australian businesses. Over 90% of cyber attacks begin with a phishing email — and they’re getting harder to spot. Business email compromise (BEC) attacks alone cost Australian organisations over $98 million in the last financial year.

We deploy enterprise-grade email security that goes far beyond basic spam filtering. Our solutions include:

Advanced threat protection that analyses attachments and URLs in real time before they reach your inbox
Business email compromise detection using AI-driven analysis of sender behaviour and email patterns
Email authentication protocols (SPF, DKIM, DMARC) properly configured and monitored
Greymail management to reduce inbox noise and improve productivity
Outbound email scanning to prevent accidental data leakage
Quarantine management with user-friendly digest notifications

We don’t just set it up and leave. We monitor your email security continuously, tune policies based on emerging threats, and provide monthly reporting so you can see exactly what’s being caught.

Phishing simulations and security awareness training

Your team is simultaneously your greatest asset and your biggest vulnerability. Even the best email filters can’t catch everything — and it only takes one click on a convincing phishing email to compromise your entire network.

We run ongoing phishing simulation programs that test your team with realistic, tailored scenarios. Not generic “click here to win” emails — we craft campaigns that mirror the actual threats targeting your industry and your business specifically.

Our training program includes:

Baseline phishing assessments to measure your organisation’s current awareness level
Regular simulated phishing campaigns with escalating sophistication
Immediate, contextual training when someone clicks — delivered at the moment of maximum receptiveness
Role-based training modules for high-risk staff (finance teams, executives, new starters)
Quarterly reporting on click rates, reporting rates and improvement trends
Board-ready reports that demonstrate measurable risk reduction over time

The goal isn’t to catch people out. It’s to build a security-conscious culture where your team instinctively questions suspicious communications and knows exactly what to do when something doesn’t look right.

Penetration testing

You can’t defend what you haven’t tested. Penetration testing is the closest thing to a real attack without the consequences — and it reveals vulnerabilities that automated scanners simply miss.

Our penetration testing services cover:

External network testing — We probe your internet-facing infrastructure for misconfigurations, unpatched services, weak credentials and exploitable vulnerabilities
Internal network testing — Simulating an attacker who’s already inside your network (through a compromised device or insider threat) to test lateral movement and privilege escalation
Web application testing — OWASP Top 10 assessment of your web applications, portals and APIs for injection flaws, broken authentication, data exposure and more
Wireless network testing — Assessing your Wi-Fi infrastructure for rogue access points, weak encryption and segmentation issues
Social engineering — Testing your human defences through phishing, vishing (phone-based attacks) and physical security assessments

Every engagement concludes with a detailed report that includes an executive summary for leadership, technical findings for your IT team, and a prioritised remediation roadmap. We don’t just tell you what’s broken — we help you fix it.

Managed detection and response

Threats don’t operate on business hours, and neither do we. Our managed detection and response service provides continuous monitoring of your environment — 24 hours a day, 7 days a week, 365 days a year.

Here’s what that looks like in practice:

Endpoint detection and response (EDR) — Advanced monitoring across all workstations, servers and mobile devices that detects malicious behaviour in real time
Network traffic analysis — Monitoring east-west and north-south traffic for anomalies that indicate compromise or data exfiltration
SIEM integration — Security information and event management that correlates logs from across your environment to identify complex, multi-stage attacks
Threat intelligence — Leveraging global threat feeds and Australian-specific intelligence to stay ahead of emerging attack patterns
Incident response — When we detect a real threat, we don’t just alert you. We contain it, investigate the root cause, remediate the impact and document lessons learned
Monthly security reporting — Clear, actionable reports that show what was detected, what was blocked, and where your posture is improving

Identity and access management

Weak passwords and over-provisioned access accounts are responsible for more breaches than any piece of malware. If a single set of credentials can unlock your entire network, your security is only as strong as your weakest password.

We implement a comprehensive identity and access management framework:

Multi-factor authentication (MFA) — Enforced across all critical systems, email, VPN and cloud services. We deploy and manage MFA solutions that balance security with usability
Enterprise password management — Centralised, encrypted password vaults that eliminate password reuse, shared sticky notes and spreadsheet-based credentials
Least-privilege access policies — Ensuring every user has exactly the access they need and nothing more, with regular access reviews
Single sign-on (SSO) — Reducing password fatigue while maintaining security through centralised authentication
Privileged access management — Additional controls for administrator accounts and sensitive systems, including session recording and just-in-time access

Cyber insurance guidance

Cyber insurance is no longer optional for most Australian businesses — but getting the right cover at the right price requires more than filling out a form. Insurers are increasingly demanding evidence of specific security controls before they’ll underwrite a policy, and claims are being denied when businesses can’t demonstrate compliance.

We help you navigate the process:

Assess your current security controls against common insurer requirements
Identify and remediate gaps that could result in denied claims or inflated premiums
Provide documentation and evidence packs for underwriter submissions
Implement the technical controls that insurers look for: MFA, EDR, backup verification, access controls and incident response plans
Review and advise on policy terms so you understand exactly what’s covered and what’s not

Our approach to security

Security isn’t a product you buy. It’s a posture you build. And it’s never finished.

We start every engagement with an honest assessment of where you stand — not to alarm you, but to give you a clear picture of your risk. Then we work with you to build a practical, phased plan that improves your defences over time, within your budget.

We stay across the Australian threat landscape so you don’t have to. We explain your risks in plain English, not scare tactics. And we measure everything — because security that can’t be measured can’t be improved.

Whether you need a one-off penetration test or a fully managed security program, we’ll tailor a solution that fits your business, your industry and your risk appetite.
