Check Point Harmony Browse
Browser Security for UK Businesses
Harmony Browse shields against zero-day phishing, malware, credential theft and data leakage – even through GenAI apps. It secures every click without compromising speed or privacy, delivering the protection a modern work environment demands.
Secure the browser your team works in every day.
Harmony Browse helps protect your business from phishing, malicious downloads, credential theft and data leakage inside the browser. It works as a lightweight browser extension, giving your team safer browsing without forcing them to change how they work.
The browser is no longer “just the internet”.
It is where people access Microsoft 365, client portals, supplier systems, finance tools, shared files, cloud apps and AI platforms. That makes browser security a serious business control, not a nice-to-have extra.
Most work now happens through a browser. Attackers know that.
A convincing login page, a fake download, a risky web app or a careless AI prompt can create a real problem. Harmony Browse is designed to protect the place where those decisions are made: the browser.
The problem
Your team are not trying to create risk. They are trying to get work done. They click links from emails, search for suppliers, download files, use cloud systems and test AI tools because that is now part of the job.
The issue is that a browser gives attackers a very direct route to your people, your passwords and your data.
What Harmony Browse does
- Blocks zero-day phishing sites in real time.
- Helps stop corporate credentials being reused on non-corporate websites.
- Checks downloads using threat emulation and file sanitisation.
- Adds URL filtering and safe search indicators.
- Helps protect sensitive data shared through web apps and GenAI tools.
- Works across major browsers using a lightweight extension.
Who Harmony Browse is for
This is for organisations that rely on cloud systems, online portals and browser-based work, but need stronger control around phishing, downloads, passwords and data leakage.
For teams that need better protection when people are using Microsoft 365, cloud apps, search engines, supplier portals and file downloads every day.
For organisations handling sensitive records where one stolen login or unsafe file could create a serious operational issue.
For education teams that want safer browsing, download protection and stronger controls without adding another admin-heavy tool.
For accountants, IFAs, estate agents, agencies and legal firms using client portals, document platforms and cloud systems.
For people working across managed and unmanaged devices where browser use can be harder to control centrally.
For businesses that want stronger evidence around phishing, malware, credential protection, web filtering and data loss prevention.
What Harmony Browse helps protect against
Harmony Browse is not just a web filter. It adds several browser-level controls around the behaviours attackers commonly exploit.
Helps block phishing sites in real time, including newer pages that may not yet be widely known as malicious.
Helps prevent corporate passwords being used on non-corporate websites, reducing the risk of stolen or reused logins.
Downloads can be checked using sandboxing and file sanitisation, helping reduce the risk from malware hidden in files.
DLP controls help protect sensitive information being shared through web applications, uploads, downloads, clipboard actions and print.
Helps manage the risk of sensitive company data being pasted or uploaded into AI tools without proper control.
Search results can be marked by safety and reputation, helping people avoid risky clicks before they happen.
Why this matters for smaller organisations
Smaller teams often run on browsers. That does not make them risky by default. It just means the browser needs to be treated as part of the security stack.
What we often see
A business has antivirus, Microsoft 365, maybe some backup, maybe MFA, and a lot of trust placed in people spotting suspicious links. That might have been enough a few years ago. It is not a comfortable position now.
Phishing pages are better. Fake login screens are more convincing. People use more cloud apps. AI tools have created another route for data to leave the business.
The better way
Keep the tools people already use, but put stronger controls around the browser. Help stop bad links, risky files, credential misuse and sensitive data sharing before they become an incident.
That is where Harmony Browse fits neatly into a managed cyber security service.
Harmony Browse and Heimdal DNS Security work well as different layers.
DNS security and browser security are connected, but they are not the same thing. Used together, they help cover more of the web attack path.
Heimdal DNS Security
Helps control access to risky domains and malicious traffic at the DNS and traffic layer. It is a strong first line of defence for blocking dangerous destinations.
Check Point Harmony Browse
Adds protection directly inside the browser, including phishing prevention, download protection, corporate credential protection, safe search, DLP and GenAI controls.
Where it fits in your wider security stack
Harmony Browse is strongest when it sits alongside the basics, not instead of them.
Your endpoint protection helps secure the device. Harmony Browse helps reduce the browser-based risks that can lead to device compromise.
Email security can stop many malicious messages. Harmony Browse gives extra protection when someone still reaches a risky link or page.
DNS filtering blocks dangerous destinations. Browser security adds controls around phishing pages, downloads, credential use and data leakage.
Training helps people make better decisions. Harmony Browse gives them a technical safety net when a threat looks believable.
Microsoft 365 is often accessed through the browser, so browser protection supports identity, email and data security controls.
Helps show that phishing, malware, data leakage and credential risks are being managed with technical controls, not just good intentions.
Common questions
The practical questions we would expect before adding another browser security control.
Does Harmony Browse replace antivirus or EDR?
No. It protects a different part of the attack path. Antivirus and EDR help protect the device. Harmony Browse helps stop browser-based threats such as phishing, risky downloads, credential theft and data leakage.
Does Harmony Browse replace DNS filtering?
No. DNS filtering is still valuable. Harmony Browse works inside the browser, where it can add controls around pages, searches, downloads, credentials, DLP and GenAI use.
Will staff need to use a different browser?
No. Harmony Browse works as an extension across major browsers, so the aim is to protect the browsers people already use rather than forcing a new browser on the business.
Can it help with AI tools?
Yes. Harmony Browse Advanced includes DLP and GenAI protection, helping reduce the risk of sensitive information being shared through AI platforms.
Is this only for large businesses?
No. Smaller organisations often rely heavily on browsers because they use cloud systems and online portals every day. That makes browser security relevant, especially where sensitive data or client logins are involved.
Can Black Swan help us decide whether we need it?
Yes. We can look at your current setup, including email security, DNS protection, endpoint security, MFA, backup, Microsoft 365 and staff training, then advise whether Harmony Browse is worth adding.
Not sure whether browser security belongs in your stack?
We can help you work it out. Book a quick security check and we will look at your current web, browser, email and Microsoft 365 risks, then suggest what is worth fixing first.
