Stop Malware Distribution
at the Domain Level
Attackers register domains that mirror your brand and host malicious downloads disguised as legitimate software. Your users trust the familiar name — and install ransomware without a second thought.
DefendDomain detects the infrastructure behind malware distribution — the lookalike domains, fake download pages, and rogue SSL certificates — before they deliver a single payload.

Real threats targeting your domainExpert consultation, not a sales pitchNo obligation
Ransomware costs organisations $4.54 million per incident on average — and 71% of malware distribution campaigns use lookalike domains to deliver their payloads.
We detect the fake download infrastructure before it delivers a single payload.
DefendDomain monitors for lookalike domains hosting malicious files, fake software update pages, and SSL certificates that make dangerous downloads look trustworthy — alerting your team before users are compromised.
Understanding the threat
How Malware Spreads Through Lookalike Domains
Malware distribution via lookalike domains works by exploiting the trust users place in familiar brand names. Attackers register typosquatted domains, build convincing download pages, and use SSL certificates to make malicious sites appear legitimate.
Drive-by Downloads
Users visit a typosquatted domain and unknowingly trigger automatic malware downloads through browser exploits or deceptive 'update required' prompts.
Partially blocked by browser security features
Malicious Email Attachments
Phishing emails with infected attachments sent from spoofed or compromised accounts directly to employee inboxes.
Filtered by email gateways and endpoint protection
Fake Software & Update Pages
Attackers register your-software-update.com and host convincing download pages with malware-laden installers. Users searching for your software find these first — and the HTTPS padlock makes them look legitimate.

Continuous monitoring with an immutable audit trail. Generate compliance reports showing proactive defence against supply chain malware risks for ISO 27001 and NIST CSF.
Why Your Current Controls Leave Gaps
Determined attackers find the blindspots in even well-configured security stacks. Here's what we hear most often — and why it matters.
"We have endpoint protection (EDR/AV)"
Endpoint detection responds after malware reaches a device. Novel payloads and zero-day exploits frequently bypass signature-based detection. DefendDomain catches the distribution infrastructure — the fake download site — before any payload is delivered.
Why detection alone isn't enough"We block malicious URLs at the firewall"
URL blocklists are reactive — they require the malicious site to be reported and classified first. New lookalike domains with fresh SSL certificates aren't on any blocklist yet. DefendDomain detects them at registration, before blocklists catch up.
Gaps in blocklist-only protection"We train employees not to download from unknown sites"
When the site uses your brand name, has HTTPS, and looks identical to your real page, it doesn't feel 'unknown.' Attackers specifically exploit brand recognition to bypass human judgement. Monitoring removes the reliance on users spotting the deception.
Why training needs a safety net"We control software installation via MDM"
MDM controls what gets installed on managed devices, but doesn't protect personal devices, contractor machines, or customer endpoints. Malware distributed through your brand's lookalike domains affects everyone who trusts your name.
Protecting beyond managed devicesFour layers of protection
How DefendDomain Stops Malware Distribution
Every fake download page needs infrastructure — a domain, an SSL certificate, cloned branding. We detect each component the moment it appears.
