Cybersecurity Services
Cybersecurity 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.
Perimeter & Firewall Security
Next-generation firewalls with hardened rules, segmented networks and managed VPN access to protect your office and remote users from external threats.
Server, Storage & Network Protection
Security hardening for servers, storage and network infrastructure, including patching, access controls and monitoring so your core business systems stay protected and available.
Endpoint Protection & EDR
Modern Endpoint Detection and Response (EDR) across laptops, desktops and mobiles to detect, contain and remediate threats before they spread across your business.
Phishing Testing & User Awareness
Simulated phishing campaigns and ongoing security awareness training help your team spot attacks early, reducing the biggest cause of breaches in small and mid-sized businesses.

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

What our Cybersecurity covers
This is the practical scope of our cybersecurity services for SMEs. If it touches your network, data, devices, users or cloud, we can assess it, secure it and support it.
Firewalls & Perimeter Security
Next-generation firewalls, segmentation, VPN and web filtering to control what gets in and out of your network. We also carry out regular firewall rule reviews so protection does not drift over time.
Server, Storage & Network Security
Hardening, patching, access control and monitoring for servers, storage and network infrastructure on-premise, co-located and in the cloud, so the systems your business depends on stay protected.
Endpoint Protection & EDR
Managed endpoint protection and Endpoint Detection & Response (EDR) across laptops, desktops, servers and mobiles, backed by monitoring and incident response when something is flagged.
Identity, Email & Cloud Security
Multi-factor authentication, conditional access, anti-phishing and data protection for Microsoft 365, Google Workspace and other business cloud services to secure identity and email, the most common attack paths.
IT Security Audits & Risk Reviews
Structured IT security audits that assess your current controls, configurations and exposures, then deliver a prioritised plan so you know exactly what to fix first to reduce risk.
Phishing & Penetration Testing
Simulated phishing campaigns, user awareness training and authorised external penetration testing that confirm where you are exposed and show how an attacker would actually target your business.

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.
