Cyber Security
Security Review and AssesmentsWe assess your current infrastructure against best practices
and emerging threats. Get a clear, actionable breakdown of
what's working, what's not, and how to improve — no jargon, no
fluff.
Security Penetration Testing and Vulnerability
ManagementOur team of ethical hackers and vulnerability analysts
can continuously or on a schedule, probe your
environment to find weaknesses before attackers do. We test,
report, and help you fix — fast.
WiFi and Network SurveyIs your wireless network secure? We’ll map your signal
coverage, identify rogue devices, and highlight any
vulnerabilities. If we find nothing — the survey is on
us.
Secure Messaging and Email, including S/MIMEDigital signatures are your frontline against phishing. We
help deploy S/MIME so your staff knows who they’re really
communicating with — no guesswork, no spoofing.
Disaster Recovery, Data Encryption and BackupsCan you recover from an outage? We run tabletop exercises and
disaster simulations to test your response and resilience.
Plus, we ensure your data is encrypted and recoverable when it
matters most.
Firewall and Router HardeningYour edge devices are the first line of defence — and often
the weakest link. We audit, harden, and configure routers,
firewalls, and VPNs with security-first principles, ensuring
attackers stay out.
Wireless Intrusion Detection and Rogue AP ScanningWiFi isn’t just about coverage — it’s about control. We
deploy wireless intrusion detection and scan for rogue access
points to ensure no one’s slipping into your network
unnoticed.
Secure Internal Infrastructure Review (Access Control &
Data Access)Who has access to what — and should they? We review your
internal systems, including user permissions, file shares, and
group policies, to identify privilege creep and access
loopholes. Ensure your data stays where it should and only the
right people can reach it.
Cybersecurity Awareness Testing and Phishing SimulationTest your team before attackers do. We simulate phishing
campaigns and social engineering attacks to reveal weak spots
in human behaviour — then educate your staff so it doesn’t
happen for real.
