BoyangCS is a cybersecurity company in Hong Kong that works with startups, SMBs, and enterprises who need someone watching their systems, not just installing software and walking away. We handle network security, cloud security, and application security, and we are usually the team called in after a business has already had a scare with phishing or ransomware. If you need a hong kong cyber partner who answers the phone when something looks wrong, that is the job we do.
As a cybersecurity solution hong kong businesses turn to when their current setup is not cutting it, we design and integrate protection tailored to what you actually run, not a generic package. Our work covers malware, phishing, DoS and DDoS attacks, and SQL injection, and we keep monitoring system performance after launch instead of disappearing once it is live.
Most Cyber security companies in hong kong sell you a package and move on. We stay involved. Every cyber security service we run includes someone actually watching your systems after setup, not just a one-time install. That is the difference between a company that sells security software and one that keeps you secure.
We provide protection against fraudulent emails or messages designed to trick owners into revealing sensitive information.
Ransomware protection hong kong businesses actually need starts before an attack, not after. We monitor for the early signs, the kind of activity that shows up hours before files start getting locked, so we can act before you are staring at a ransom note.
Our team of cybersecurity experts provides complete protection against malicious software such as viruses, ransomware, and spyware.
Our cybersecurity services also include protection against SQL Injection attacks. In this cyber attack, malicious SQL code is inserted into database queries to manipulate sensitive data.
We are one of the hong kong cybersecurity companies that has actually been in the room when something went wrong, not just the brochure. We have worked across China and Hong Kong on complex, high-stakes security projects for nearly a decade. Whatever your security needs look like, we have the experience, the tools, and the team to take it on.
As your network security service provider, we watch your wired and wireless network around the clock, not just at setup. Firewalls and intrusion detection systems catch what they catch, but most breaches happen because nobody was watching the alerts those tools generated. We are the ones watching.
We’re one of the most experienced cloud security companies, offering holistic protection against any attempt to breach data or information stored in the cloud. Our experts design and implement advanced encryption protocols, secure access controls, and continuous monitoring systems to ensure your cloud environment stays protected at all times.
Application Security focuses on protecting your software and applications from vulnerabilities throughout the development lifecycle and beyond. We implement secure coding practices, regular code audits, and vulnerability testing to identify and fix potential threats. Our goal is to ensure your applications remain secure, reliable, and resistant to cyber threats.

Yes, we provide comprehensive security monitoring for all your systems and software to ensure ongoing protection against potential threats. With this service, you can make sure that any hacking or data breaching can be stopped before it starts becoming a serious problem.
We layer protection instead of relying on one tool. That means firewalls and intrusion detection on your network, encryption and access controls on anything stored in the cloud, and regular testing on your applications to catch weak points before someone else finds them. No system is unbreakable, but layered protection is what stops most attacks before they go anywhere.
It depends on what you need monitored and how much data you are protecting. A small business with one office network costs less to protect than an enterprise running cloud infrastructure across multiple sites. We scope every cybersecurity service around what you actually have to lose, then quote a number, not a range. Reach out and we will tell you what it costs.
We’ve been providing cybersecurity services for nearly a decade, working with both small businesses and large enterprises on a wide range of security projects.
Firewalls, intrusion detection systems, and traffic across your wired and wireless network, all day, every day. Most breaches do not happen because nobody had security software. They happen because nobody was watching the alerts it generated. As your network security service provider, that watching is the actual job.
We are building out brand protection as part of our security offering, covering things like unauthorised use of your company name or assets online. As a brand protection company hk businesses are starting to ask about more, we want to be upfront that this side of the business is still growing. If brand protection is what you need right now, talk to us directly so we can tell you exactly what we can take on today versus what is still coming.
Call us, email us, or fill out the form on this page. For cybersecurity contact during business hours, expect a response the same day. If you are dealing with an active incident, say so up front so we can prioritise the call.
Every cybersecurity service we run starts with the same question: what do you actually have to lose. A manufacturer worried about operational systems needs a different setup than a fintech worried about transaction fraud. We build around that instead of selling the same package to everyone.
