Stop Smishing Attacks
at the Source
Phishing has moved to text messages. Attackers send SMS links to lookalike domains optimised for mobile screens — where users can't see the full URL and your email gateway has zero visibility.
DefendDomain catches the mobile-optimised phishing domains before they're sent to a single phone. Your email gateway can't help here — we can.

Smishing attacks have surged 328% — and SMS phishing has an 8x higher click rate than email because users inherently trust text messages and can't inspect URLs on mobile screens.
We detect the domains before they're texted to anyone.
DefendDomain monitors for the mobile-optimised lookalike domains that smishing campaigns rely on — catching them via Certificate Transparency and DNS monitoring the moment they go live, before a single text is sent.
Understanding the threat
What is Smishing?
Smishing (SMS phishing) is a cyber attack where adversaries send text messages containing links to malicious websites on lookalike domains. Mobile browsers hide full URLs, making it nearly impossible for users to spot typosquatted domains on their phones.
Carrier-Level Filtering
Mobile carriers apply basic spam filters to block known malicious numbers and URLs, but can't inspect new domains or detect brand impersonation in message content.
Limited to known threat signatures
Corporate MDM Controls
Mobile Device Management can restrict app installs and enforce security policies on managed devices, but can't prevent users from clicking SMS links or entering credentials on web pages.
No visibility into SMS link destinations
Lookalike Domain Smishing
Attackers register your-brand-verify.com, build a mobile-optimised phishing page, and blast SMS links. Mobile browsers truncate URLs so users see only 'your-brand...' — the perfect disguise.

Why Different Teams Choose DefendDomain
From the boardroom to the SOC floor, every team has a different reason to monitor for domain threats.
CISOs & Security Leaders
Close the mobile phishing gap your email gateway can't reach
Smishing bypasses every email-based control. DefendDomain extends your visibility to the mobile attack surface with automated domain monitoring and board-level reporting.
Digital & Mobile Teams
Protect customers who interact with your brand via mobile
If your business sends legitimate SMS communications — notifications, 2FA codes, marketing — smishing attacks exploit that trust. Monitor for domains that impersonate your mobile touchpoints.
IT Directors & Heads of Risk
Extend security beyond managed devices
Personal phones, contractor devices, and BYOD endpoints are all smishing targets. DefendDomain catches the threat at the domain level — before it matters which device the link is opened on.
Compliance & Regulatory Teams
Demonstrate proactive mobile threat monitoring
Smishing increasingly triggers regulatory obligations — especially in financial services and healthcare. Continuous monitoring with full audit trails satisfies compliance requirements for external threat management.
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 a secure email gateway"
Email gateways protect corporate inboxes but have zero visibility into SMS channels. Smishing attacks target personal phone numbers, bypassing every email-based security control you've invested in. The attack surface has moved — your detection needs to move with it.
Gaps in gateway-only protection"We use MDM on company phones"
MDM controls what apps run on managed devices, but can't prevent users from clicking an SMS link and entering credentials in a mobile browser. And many employees access work resources from personal devices that MDM doesn't touch.
Why MDM alone isn't enough"We've set up SMS sender verification"
Sender verification confirms your legitimate messages, but doesn't stop attackers from sending smishing texts from different numbers. Victims click because the linked domain looks right, not because they verified the sender number.
Why sender verification needs a safety net"We train employees to spot phishing"
Training helps with email phishing where users can hover over links and inspect URLs. On mobile, URLs are truncated, there's no hover preview, and the urgency of text messages overrides trained caution. Training needs a technical safety net.
Why training alone falls shortFour layers of protection
How DefendDomain Stops Smishing
Every smishing campaign needs a destination — a lookalike domain with an SSL certificate and a mobile-optimised phishing page. We detect each component the moment it appears.
Layer 1
Domain Monitoring
Proactively monitors for lookalike domains that could be used to impersonate your brand. Our AI generates thousands of domain variations including typos, homoglyphs, and keyword combinations, then continuously scans for registrations.
- Detects typosquatting and phishing domains
- Monitors domain registrations in real-time
- AI-powered threat scoring and prioritization
- Automated evidence collection for takedowns
