Free DNS Security Evaluation
Free DNS Security Evaluation to measure the real security coverage of your recursive DNS filtering stack.
Dohzel Proxy includes a built-in evaluation tool that allows organizations to test the effectiveness of their DNS security controls against real malicious, phishing, typo-squatting, and brand-abuse domains.
Instead of relying on vendor claims alone, teams can quickly assess how well a recursive DNS service actually blocks known threats.
Move from assumptions to measurable DNS protection
Many organizations deploy DNS filtering as a first layer of protection, but few have a practical way to verify how effective that protection really is.
With DNS Security Evaluation, directly integrated into Dohzel Proxy, security and infrastructure teams can run controlled checkups against a recursive DNS service and measure its actual blocking performance.
- evaluate the coverage of an existing DNS security provider
- compare recursive DNS filtering services
- validate policy effectiveness after deployment or migration
- identify blind spots in phishing, typo-squatting, and malicious-domain protection
- support security assessment and purchasing decisions with measurable results
Built-in assessment tooling inside Dohzel Proxy
Dohzel Proxy embeds a native command-line capability that tests a recursive DNS service against a curated set of suspicious or malicious domains.
Domain response behavior
- resolved normally
- blocked by sinkhole or blocker IP
- inconsistently filtered
- passed without protection
Clear measurable summary
- number of tested domains
- blocked domains
- passed domains
- observed response times
- overall DNS security coverage
DNS filtering is often trusted, but rarely measured
DNS security is widely used as a foundational control, yet many deployments are accepted with limited evidence of actual effectiveness.
A resolver may appear operational while still allowing:
- phishing infrastructure
- typo-squatted domains
- fraudulent lookalikes
- cloud-hosted malicious assets
- suspicious domains linked to brand abuse or credential theft
DNS Security Evaluation helps organizations determine whether current controls are effectively blocking harmful domains and aligned with expected risk coverage.
Simple, fast, and operationally practical
The evaluation capability is built directly into Dohzel Proxy and can be launched from the command line with configurable test volume.
Example workflow
- target a recursive DNS server
- define the number of test domains
- configure expected blocker IP behavior
- run the assessment
- review detailed results and global coverage score
Output includes
- tested domain list
- returned IPs
- blocked / not blocked status
- per-query timing
- final protection summary
How it looks in practice
Dohzel Proxy includes a built-in command to run a DNS security checkup against a recursive DNS server.
Example: testing a public recursive DNS service. In observed runs, tested resolvers resolved all tested domains and blocked none, resulting in 0.00% DNS security coveragefor the selected sample.
DNS resolution performance is not the same thing as DNS security effectiveness.
Native operational tooling
Available capability
- run recursive DNS filtering assessments
- configure block IP expectations
- adjust tested domain volume
- control delay between DNS queries
Typical usage
- evaluate a provider before deployment
- validate a migration
- benchmark multiple DNS filtering services
- support security reviews and procurement processes
- verify expected protection in production-like conditions
Why organizations use DNS Security Evaluation
Validate third-party DNS security claims
Go beyond marketing promises and verify actual blocking behavior with direct testing.
Benchmark providers objectively
Compare multiple recursive DNS services on measurable security outcomes, not only speed or feature lists.
Support architecture decisions
Assess whether a DNS filtering layer is sufficient on its own or should be reinforced with additional controls.
Expose blind spots early
Identify gaps in phishing, typo-squatting, and malicious-domain protection before they become incidents.
Improve security governance
Provide security, IT, and procurement teams with concrete evidence to support decisions and periodic reviews.
A practical assessment layer for existing environments
DNS Security Evaluation is not designed to replace your current DNS security controls. It is designed to help you measure them, challenge assumptions, and understand their real level of protection.
Common use cases
Why this matters in Dohzel Proxy
Because the evaluation tool is built directly into Dohzel Proxy, teams do not need a separate assessment platform to begin testing recursive DNS security behavior.
- operational simplicity
- rapid execution
- direct field validation
- measurable results tied to real DNS behavior
Test your DNS protection with evidence
Assess recursive filtering coverage, identify blind spots, and validate whether your DNS layer is really protecting users, systems, and critical environments.
