Email filters are not enough. Attackers know exactly where the gap is.
Most email attacks succeed after they reach the inbox, not before. The click is the moment of risk. Post-delivery link protection is what your existing security stack is missing.
Assume the Click. Eliminate the Risk.
Traditional security focuses on detection before delivery. CyberCheck360 protects users after emails arrive and when links are clicked, using safe sandbox-based browsing to isolate threats entirely.
Detection Based Security
- Tries to guess if a link is bad
- Relies on outdated signatures
- Fails when reputation is unknown
- Links that turn malicious after delivery bypass it entirely
- One miss exposes the device and network
Isolation Based Protection
- Opens links in a secure remote browser regardless
- Malware never touches the endpoint
- 100% protection from zero-day exploits at the link level
- Post-delivery changes are irrelevant. Execution always isolated.
- Works alongside your existing email filter, not instead of it
You clicked a malicious link.
Here is exactly what happened next.
Every email security strategy assumes users will eventually click something they should not. The question is not whether a malicious link gets clicked — it is what your security does in the 400 milliseconds after that click.
Your browser begins loading the destination URL directly on your device.
A credential harvesting form, exploit kit, or drive-by download begins executing on your machine.
If you type anything — or even if you do not — session tokens and browser data may already be harvested.
The attacker now has a foothold. Your device is compromised. Your network is the next target.
Your IT team finds out hours or days later, after real damage is done.
An email arrived. It looked legitimate. You clicked. That moment right there is where every modern phishing attack begins.
Before the destination page can load on your device, your click is silently routed through our isolation layer. You notice nothing. The attacker notices everything has gone wrong.
The credential harvesting page loads. The exploit fires. The malware unpacks. All of it happens inside a disposable container in our cloud. Your device is not involved.
You're shown the destination content inside our isolated browser — domain age, sender analysis, threat verdict. You can read. You can browse. Nothing real is at risk.
The session closes. The container is wiped. Whatever the attacker loaded — ransomware, a keylogger, a credential form — is gone. Your network never saw it.
The click is unavoidable. What matters is what your security does in the 400 milliseconds after it happens. CyberCheck360 makes the destination irrelevant — safe or malicious, nothing executes on your device.

Zero-trust protection for every click. Silent. Automatic. Instant.
With Link Rewriting enabled, every email link your organisation receives is automatically rewritten and isolated before anyone clicks. Users work exactly as before. Protection happens in the background.
Why build a link sandbox when you can use a managed service?
Building your own link sandbox infrastructure is technically possible. Here is what it actually costs compared to a fully managed link isolation service.
Works Alongside Your Existing Security
CyberCheck360 is post-delivery link isolation that works alongside Microsoft Defender, Mimecast, Proofpoint and any email gateway. When a threat bypasses your filter, we protect the click. No rip and replace required.

Email filters and Defender work at delivery. They block emails they recognise as malicious based on known signatures. CyberCheck360 works at the click, the actual moment of risk. When a phishing link gets past your filter, and statistically some will, we isolate it in a remote cloud browser before anything reaches your device or network. We are post-delivery link protection, not a replacement for your email gateway.
Without link isolation, clicking a phishing link can execute malware on the device within seconds, harvest credentials from a fake login page, or give attackers a foothold into your network. With CyberCheck360, the link opens in our isolated cloud browser instead of the device. Whatever the site does, it happens in the cloud. The employee sees a block page and the device stays completely clean.
No. Even the best email filters let through 1 to 5 percent of phishing attempts, because they rely on known signatures and reputation data. Polymorphic phishing links change their payload after delivery, so they appear clean at the time of scanning. Zero-day threats have no reputation at all. CyberCheck360 protects against what the filter misses by isolating every link at the moment of the click, not just at delivery.
Browser isolation runs the web content of a link in a remote cloud environment instead of on the user's device. The user sees and interacts with the page normally, but the actual code, scripts and files execute in our cloud. If the destination is malicious, the threat is fully contained. Nothing from the page can reach the device or the network. CyberCheck360 applies this specifically to email links, making it the most targeted and efficient form of protection for the highest-risk click in any organisation.
No. With Link Rewriting enabled, protection is completely invisible to users. They click email links exactly as they always have. Every click is automatically routed through our isolated cloud browser in the background. There is nothing to install on individual machines, no new interface to learn, and no behaviour change required from anyone in your organisation.
The on-demand sandbox is for deliberate checking. Your security team or IT staff paste a suspicious link or upload a file to investigate it before deciding what to do. Link Rewriting is automatic zero-trust protection for your whole organisation: every email link is rewritten at delivery so every click by every user is isolated automatically, with no action required. Most organisations start with the sandbox to experience isolation, then add Link Rewriting for full coverage.
Yes. When a user clicks a rewritten link, they see the destination URL, the domain age, and the safety verdict. If they recognise and trust the sender, they can raise a request to open the link locally. That request goes to the admin dashboard for approval. This keeps your security team in control without blocking users from doing their jobs.
The Outlook and Gmail add-ins deploy in minutes via your admin console with no changes to individual machines. Link Rewriting can be enabled org-wide by a single admin from the same console. Most organisations are fully live the same day they sign up. There is no infrastructure to provision and no engineering resource required.
Mimecast and Proofpoint are detection-based. They scan emails against known threats at delivery. CyberCheck360 is isolation-based: it protects your users at the click, regardless of whether the threat was known at delivery. The two approaches solve different problems and work together. When a phishing email gets through your gateway, CyberCheck360 is what stops the click from causing damage.
Yes. Link Rewriting is a direct implementation of the zero-trust principle applied to email links: never trust a link, always verify and isolate. Every link is treated as potentially malicious regardless of sender reputation or prior safe status. This aligns directly with NIST zero-trust architecture and is a natural fit for organisations adopting a zero-trust security model.
Yes, this is exactly who we built it for. You do not need a SOC, a threat analyst, or a dedicated security engineer to run CyberCheck360. The sandbox gives your IT manager the ability to investigate suspicious links on demand. Link Rewriting protects every user automatically without anyone having to do anything. The admin dashboard gives visibility without requiring expertise to interpret it.
We offer private managed sandbox environments for SOC teams and MSSPs who need link and file isolation at volume without the end-user email add-in experience. This is a custom arrangement, so reach out to our team and we will put together the right setup for your use case.
Protect Every Click. Stop Every Threat.
Your email filter stops what it recognises. CyberCheck360 protects you from everything it does not, at the moment of the click.
