How to use the domain security tool
- Complete a domain lookup by entering any domain name into the provided field. The tool requires a domain name and TLD (e.g., example.com). The protocol and ‘www’ subdomain aren’t required.
- Click Analyze. Our tool will query the WHOIS database and locate the most recent records.
- Get your results in seconds for free.
Your domain lookup results will appear below the tool. You can also export your results for local access.
Why domain security matters
Everyone is on the internet – and that includes bad actors, malicious threats, and worse. Thankfully, the Internet Corporation for Assigned Names and Numbers (ICANN) helps to protect against threats by publicly listing domain WHOIS information for all websites and senders.
Domain security benefits you by:
- Securing your website against hijackers – Protect your website from hackers and cyberattacks that can compromise your data, business, and customer information.
- Email protection – Identify and isolate senders looking to impersonate your business and email domain to deceive subscribers and steal information.
- Consumer trust and brand reputation – Most internet users are savvy and smart. If your domain isn’t secure, your brand reputation suffers as potential customers will see that your website and emails are suspicious and untrustworthy.
- Data security and privacy compliance – Once you acquire customer data, you’re responsible for who may access it. Businesses must use modern domain security protocols to mitigate unauthorized access to this information.
- Business asset and final protection – If your domain isn’t secure, you’re a sitting duck for online threats. It won’t take much for a cyberattack to steal your data, granting them access to vital records, including customers, banking, partners, and others.
What you can check
The free domain analyzer allows you to check domains for vital information, including history, domain health checks, and domain security records, such as:
- WHOIS info – Check domain registration and related information, including domain age, traffic rank, registrar, CDN, and email provider.
- Domain status – Check domains for WHOIS privacy status along with a domain health check for reputation score and current real-time blackhole (RBL) status.
- DNS records and related issues – The domain scanner accesses email and website security records, including:
- DMARC, SPF, BIMI, and MTA-STS
- SSL Certificate, TLS, HSTS, and CAA
- DNSSEC and any present DNS servers
- Subdomains – The domain lookup can also discover any subdomains associated with the primary domain. You can then perform another free lookup for any subdomains you want to check.
Common use cases
- Domain security checks and compliance research – Find out if websites you’re visiting are secure and protected, especially if you’re uploading or providing sensitive data. It’s also helpful for ensuring that sellers or partners are compliant with the data you share.
- Threat detection – Unsure if a website or an email is legitimate? Perform a domain lookup and find out if it’s legitimate and protected, or if you’re the target of a possible attack or phishing scam.
- Domain health checks – In addition to threat detection, a domain security check will tell you more about a domain’s health, including if it’s currently in violation of any rules or regulations that earn it a spot on an internet blacklist.
- Business development – Struggling to find contact information for a prospective customer? You can identify the business owner and obtain their contact information by accessing WHOIS information through a domain lookup. Please note that not all personal information is publicly available, and the owner may choose to set this information to private.
- Domain acquisition – If you’re looking to purchase or change domains to an existing one, you can find out who owns the domain with a WHOIS lookup. Again, not all personal data is listed in the WHOIS record, but you will know who the registrar is and if the domain is currently active.
