Cybersecurity Services Hong Kong

Practical cybersecurity for SMEs in Hong Kong, China and APAC

PTS helps small and mid-sized businesses protect users, data and systems with layered cybersecurity that covers the network perimeter, servers, storage, endpoints and the cloud. We combine firewalls, monitoring, endpoint protection and structured testing so you know what is protected, where your risks are, and what to fix first.

From IT security audits and firewall hardening to phishing simulation and external penetration testing, we deliver cybersecurity services that are proportionate, explainable and built for business owners, not just technical teams.

Practical guides: how to protect your business from phishing attacks, the 19 cybersecurity policies every business needs, and AI scams in Hong Kong.

What we cover

Network & Perimeter Security

Protect the front door of your business with layered network and perimeter security designed for SMEs that cannot afford downtime or data loss.

• Managed firewalls Next-generation firewalls with proper rules, segmentation and logging, not default configurations that leave gaps.
• Secure remote access VPN and zero-trust access so staff working from home or on the road connect safely to internal systems.
• Web & DNS filtering Block malicious sites, phishing links and known bad domains before they reach users or devices.
• Wi-Fi & guest network hardening Separate staff, guest and device networks with strong authentication and monitoring.
• Firewall rule reviews Regular reviews of firewall rules and access policies to remove stale exposures and reduce your attack surface.

Endpoint, Server & Data Protection

Secure the devices and systems where your business actually runs, with modern endpoint protection, EDR and hardened server and storage configurations.

• Endpoint Detection & Response (EDR) Advanced endpoint protection that detects, isolates and remediates threats on laptops, desktops and servers.
• Server & storage hardening Secure configuration, patching and access controls for on-premise, hybrid and cloud servers and storage.
• Identity & access management Strong passwords, multi-factor authentication and least-privilege access across Microsoft 365 and core systems.
• Backup & ransomware resilience Reliable, tested backups so you can recover from ransomware, accidental deletion or hardware failure.
• Email & cloud security Advanced filtering, anti-phishing and monitoring for Microsoft 365, Google Workspace and business email.

Security Testing, Audits & Awareness

Understand where you really stand. Our IT security audits, phishing testing and external penetration testing give you an honest picture of risk and a clear plan to fix it.

• IT security audit Structured review of your systems, users, policies and configurations against practical SME security benchmarks.
• External penetration testing Authorised testing of your public-facing systems to identify vulnerabilities before attackers do.
• Phishing simulation & awareness Realistic phishing campaigns and training that help staff recognise and report real attacks.
• Risk & compliance support Practical guidance on PDPO, ISO, cyber insurance and client security questionnaires.
• Clear remediation roadmap Every engagement delivers a prioritised list of actions, owners and timelines, not just a report.

Cybersecurity FAQs

What is included in your cybersecurity services?

Our cybersecurity services cover perimeter and firewall security, server, storage and network protection, endpoint protection and EDR, identity and email security, IT security audits, phishing simulation and external penetration testing, tailored for small and mid-sized businesses.

Are your cybersecurity services suitable for SMEs?

Yes. Our services are designed for small and mid-sized businesses that need practical, layered protection without an in-house security team. We focus on the controls that deliver the biggest reduction in real-world risk for your size and industry.

How does an IT security audit work?

We review your users, devices, network, servers, cloud services, backups and policies against proven security benchmarks. You receive a clear report with risk ratings and a prioritised remediation plan so you know exactly what to fix first.

What is EDR and do I need it?

Endpoint Detection & Response (EDR) is a modern replacement for traditional antivirus. It detects suspicious behaviour, isolates compromised devices and supports rapid response. For most SMEs today, EDR is a baseline requirement, not an optional extra.

Do you carry out phishing testing and user awareness training?

Yes. We run realistic phishing simulations and ongoing security awareness training so your team learns to spot and report real attacks. Phishing remains the most common entry point for breaches in SMEs, so regular testing is essential.

Can you perform external penetration testing?

Yes. Our authorised external penetration testing probes your internet-facing systems to confirm what an attacker could actually exploit. You get a technical report, an executive summary and clear remediation guidance for your team.

How do we get started?

Most engagements start with a short security review or IT security audit so we understand what you already have in place. From there, we agree a prioritised plan covering firewall rules, endpoints, identity, backups, testing and training that fits your budget and business risk.
