Post-Delivery Email Security

Close the gap your email filter leaves open.

Every phishing link and suspicious attachment that slips past your gateway opens inside a disposable cloud browser. Nothing touches your endpoint.

The problem

Your filter blocks what it recognises. The rest gets through.

Between 1 and 5 percent of phishing bypasses even the best pre-delivery filter. Every one of them lands in an inbox your gateway has already cleared.

01

The human click

Training reduces rate. One user under deadline pressure. Technical control is the only reliable answer.

02

Polymorphic phishing

Clean at delivery. Weaponised hours later. Filter verdict already cached.

03

Zero-day URLs

No reputation on domains registered days ago. Unknown threats walk straight through.

0ms

The window between a click and endpoint compromise. Everything before it is prevention. Everything after it is incident response. CyberCheck360 owns the milliseconds in between.

Post-Incident

When something gets through, you have minutes. Not days.

Correlating SIEM logs, Exchange traces, and firewall data takes days. CyberCheck360 shows the full picture in seconds.

Every isolation, logged in context

User, Device identifier, verdict, and destination URL. Captured automatically on every isolation.

Blast radius in seconds

One filter on the URL returns every user who clicked, from every host. Containment starts immediately, not after correlation.

MTTR that fits a board slide

Days of correlation work becomes a single query. Response in minutes, not shift handovers.

FAQ

Frequently Asked Questions

Real questions from IT managers, security leads and CISOs before they book a demo. Not here? Talk to us.

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.
