2. DNSTwist

3. DNSlystics

4. Virustotal

Bolster provides automated detection and takedown of phishing content and spoofed websites and can even offer suggestions for URLs to register that typosquatters might try and use. Bolster is one of the most comprehensive Zerofox Competitors.

In real-time, Bolster uses AI-based detection to scan websites, domains, social media, app stores, and the dark web. They scan to see if your logo and images are being used to impersonate your website and scan search engines for malicious ads and search results.

Bolster offers several dashboards allowing collaboration among your brand, fraud, and security teams. Setup time is measured in minutes, as there’s nothing to install on your end.

Scanning is automatic, and detection can occur within milliseconds, with scam sites being taken down within minutes.

DNSTwist can detect typosquatters, phishing attacks, fraud, and brand impersonation URLs. It has a website permutation engine that creates variations of your domain and then checks if those URLs are in use. DNSTwist offers two versions, a command-line Linux-based installation or, if “you’re in a hurry,” a browser-based version.

Although the CLI-based program can generate millions of URL permutations, it limits itself to those “very close to the original one” because of resource use.

Once the scan is complete, the returned data is structured as a quickly processed list of dictionaries. The web version can export the results to a JSON or CSV file for your review and use.

DNSTwist can also check for rogue mail servers that attempt to intercept emails sent with a typing error in the address.

While DNSTwist generates a list of fraudulent websites, it does not do remediation.


The DNSlystics research tool allows you to track down information about a URL, such as IP, geolocation, DNS, and MX records. It also facilitates reverse lookups, such as IP and nameservers, and domains sharing the same Google Adsense or Analytics IDs.

Monitoring is done via keywords like your trademark, brand name, product name, or any other keyword string. Thus, search results will be only as good as your queries. DNSlystics allows you to create searches but does not automatically generate URL permutations to check for alternative spellings of your domain.

DNSlystics offers automated brand monitoring services, sending an email alert when it detects a new domain containing the keyword string noted above. Its DNS Alerts send an email when an IP address, mail server, or nameservers for your domain is added, changed, or removed.

Scans for both services are conducted every 24 hours, and IP/DNS data is refreshed every 30 days. DNSlystics does no remediation and is available in both ad-supported and paid versions.


DNSRazzle is another tool to detect typosquatting and brand impersonation domains. It uses the DNSTwist engine to generate domain variations and then checks whether those domains are in use. DNSRazzle can also detect phishing and brand impersonation sites by creating screenshots of the discovered domains and comparing them to your original domain.

DNSRazzle saves output data as a text file, and screenshots are put into a dedicated screenshot folder. DNSRazzle does not do any remediation.

OWASP Domain Protect

OWASP Domain Protect is used to prevent the takeover of your website subdomains by continually scanning for DNS records vulnerable to takeover. Cybercriminals often use subdomains to host malware, harvest credentials, and damage your reputation.

When OWASP detects a vulnerable subdomain, the program alerts you via email or Slack so you can take action. OWASP Domain Protect does not detect typosquatting, phishing, or similar websites or activities and, therefore, offers no remediation of any issues discovered.


PhishTank is a community-based phish information clearinghouse where registered users can submit, verify, track, and share phish data. Users vote on submitted phishing sites whether they believe the URL is a phish, which can take some time to finalize.

While new user registration is closed for the foreseeable future, you can still query the database to check if the community has information on a specific URL. Because it’s now an information repository only, it offers no direct protection, nor does it perform any remediation. PhishTank has limited features and is not as comprehensive as other Zerofox competitors.


VirusTotal aggregates various online scan engines and antivirus products submitted by contributors. These security vendor data sources allow you to submit suspect URLs or files to check for known security issues, including issues your anti-virus software may have missed.

VirusTotal is a browser-based tool for manually submitting URLs, but you can install it locally. An API is available for automating the submission and scanning of URLs and outputs the results via JSON. It offers no remediation capabilities. Like PhishTank, Virustotal has limited features and is less comprehensive than other Zerofox competitors.

Other Alternatives

Other Zerofox alternatives are Recorded Future, Digital Shadows, and RiskIQ. However, none of these vendors are complete digital risk protection platforms like They are mostly threat intelligence vendors who provide a list of URLs and takedowns, and remediations are outsourced to a third-party vendor such as FraudWatch. It makes it incredibly difficult to track the progress of takedowns.

Conclusion, ZeroFox, and others are helping companies combat significant threats to website security that can damage customer confidence and lead to fraud, malware drive-bys, and social engineering scams. These solutions offer a range of tools and services, including automated detection and takedown of malicious content wherever it may be hosted.
