External exposure monitoring for SMEs and lean IT teams
Know what attackers can see. Fix the risks that matter first.
NetDefenders checks your public-facing websites, domains, email security, exposed services, breach exposure and other visible risks — then turns the findings into plain-English actions your business can understand.
Start with instant website, DNS and email checks. No agents required. Safe external checks under a responsible scanning policy. Deeper testing is scoped separately.
What happens after you start?
Start safely in three steps
The first step should feel simple, clear and low-risk. You start with the basics, then deeper exposure monitoring appears inside the portal as checks complete. Review the responsible scanning policy before starting.
Add what you know. You do not need a full asset list to begin.
See basic website, DNS and email security checks first.
Exposure, breach, service and asset findings populate as scanning completes.
What NetDefenders checks
One view of the public-facing risks attackers could use
NetDefenders brings together the common external signals that matter to SMEs, then explains the result in a way business owners and IT providers can both act on.
Your website
Checks common website risks, exposed technology, unsafe behaviour and security headers.
Your domains and DNS
Finds weak email protection, spoofing risks and DNS misconfigurations.
Your exposed services
Identifies public-facing systems such as remote access, mail servers and open ports.
Your public footprint
Finds domains, subdomains, public records and exposed information attackers could discover.
Your breach exposure
Checks whether company email addresses or credentials appear in known breach data.
From visibility to action
Not just more alerts. A clearer priority list.
Most businesses do not need another technical report they cannot use. They need to know what is exposed, what it means, and what should happen next.
Raw finding vs useful action
Most tools give you a list. NetDefenders shows what to fix first.
Technical findings can be accurate but still unhelpful. NetDefenders converts them into practical business language, likely impact and next steps.
Apache 2.4.49 < 2.4.50 — multiple vulnerabilities
Affected asset: example.com
Suggested solution: Upgrade Apache to version 2.4.50 or later.
Your web server software appears out of date
This could increase the risk of website compromise, downtime, or unauthorised access if a known issue is exploited.
Business impact: Your website could become unavailable, defaced, or used as a route into other systems.
- Prioritise this if it is internet-facing.
- Confirm whether the server is managed by your host or your team.
- Upgrade, restart the service, then re-check the version.
sudo apt update
sudo apt install --only-upgrade apache2
Credential exposure identified in public breach data
Account: [email protected]
Status: Appears in one or more breach datasets.
A company email address may have been exposed
This does not automatically mean your systems were hacked, but it may increase the risk of account takeover or phishing.
Business impact: This could increase the chance of invoice fraud, mailbox compromise or targeted phishing.
- Force a password reset for the affected account.
- Check for password reuse elsewhere.
- Enable multi-factor authentication and review login history.
Remote access service detected on the public internet
Service: RDP / remote login service
Host: remote.example.com
A remote access system appears publicly exposed
Services like this are commonly targeted by password spraying, brute-force attempts and configuration weaknesses.
Business impact: Attackers often target remote access systems to break into company networks.
- Restrict access to VPN or trusted IP addresses.
- Disable the service if it is not needed.
- Enforce MFA and review account lockout settings.
Missing or weak SPF / DMARC email protection
Domain: example.com
Status: Policy missing or not fully enforced.
Your email domain may be easier to spoof
Attackers may be able to send emails that look like they came from your company.
Business impact: Criminals may impersonate your company to target customers, suppliers or staff.
- Review and correct your SPF record.
- Add or strengthen your DMARC policy.
- Monitor reports before tightening enforcement.
How NetDefenders works
From first scan to meaningful action
Start with what you know. NetDefenders finds what is exposed, explains what matters, helps route the fix, and keeps watching for changes.
Tell us what you know.
Add your website, domains and known public IP addresses. You do not need a perfect asset list or a dedicated security team to begin.
We find what is exposed.
NetDefenders checks visible assets, exposed services, DNS, email security, breach signals and website risks. This gives you a clearer view of what attackers could already see.
You see what matters first.
Findings are prioritised by likely business impact, not just technical severity. Owners see what the risk means, and IT teams see what to fix.
We help route the fix.
Remediation Support adds tailored guidance so the issue can go to the right person, whether that is your site admin, email provider, hosting support, IT provider or internal team. This reduces wasted back-and-forth.
We keep watching.
Every automated tier includes at least weekly scanning. Growth Monitoring and Remediation Support add continuous scanning for key exposure changes. Security becomes an ongoing view, not a one-off report.

NetDefenders monitoring helps you spot and prioritise externally visible risks on an ongoing basis. Manual penetration testing is useful when you need deeper human-led assurance.
Quick answers
Questions before starting?
Short answers to the questions most businesses ask before starting the trial. The full FAQ page can cover the deeper details.
Do I need to install anything?
No. NetDefenders checks your externally visible websites, domains, services and public exposure. No agents are required for the standard monitoring plans.
What happens during the 30-day trial?
You get instant basic checks first, such as website headers, DNS and email configuration. Deeper exposure checks take longer and populate inside the portal as scans complete.
Is this the same as a penetration test?
No. NetDefenders provides continuous external exposure monitoring. Manual penetration testing is available separately when you need deeper human-led assurance or compliance evidence.
Will the results be too technical?
No. Findings are translated into plain English with priority, business impact and practical next steps.
Can my IT provider use the results?
Yes. The findings are designed to be understandable for business owners while still giving IT providers enough detail to take action.
Is scanning safe?
The platform is designed for external exposure monitoring and low-impact checks. Higher-depth or manual testing is scoped separately. See the responsible scanning policy.
