Every week, legitimate business owners find themselves blacklisted. Not because they did anything wrong, but because automated security systems flagged them based on incomplete signals. Traffic stops. Emails bounce. They are stuck trying to figure out which provider flagged them, how to contact them, what documentation to provide. Some providers never respond.
The consequences are significant. Website traffic fully stops or gets partially blocked. Critical business emails are marked as spam. Revenue losses mount by the hour while they search for answers.
This pattern plays out at every scale, from companies with a handful of domains to enterprises managing portfolios of hundreds or thousands. The frustration is universal. For enterprises managing 500+ domains, one blacklist can cascade across the entire portfolio. What starts as one issue becomes twelve by the next morning, each requiring individual removal requests.
That is why we built Reputable Domains.
The Prevention Layer the Industry Needed
After years of watching legitimate businesses struggle with blacklist issues, we created what should have existed all along: a human-verified whitelist platform that prevents false flagging before it happens.
Reputable Domains provides verified brand-domain associations distributed to abuse report producers and receivers worldwide. It is not about fixing blacklist problems after they occur. It is about preventing them in the first place.
Today, it is live at reputable.domains.
Why We Built This
Our founding team comes from iQ Global, where they spent 8 years operating abuse management infrastructure for 175+ registries and registrars, processing 250 million domains daily. That experience gave us visibility into the entire abuse reporting workflow, and the gaps that legitimate businesses fall through.
Abuse report producers (threat intelligence companies, blocklist providers) work to detect and report potential threats. Automated detection systems sometimes flag legitimate domains based on weak signals or incomplete evidence. This is a challenge facing everyone in threat intelligence.
Abuse report receivers (registrars, hosting providers, ISPs) process hundreds or thousands of these reports daily. They are overwhelmed. Industry research shows average reaction times exceed 3 days, with only 2% of providers responding within an hour (abuse.ch). Their abuse desks are understaffed, mailboxes overflow, and they struggle to distinguish legitimate concerns from noise.
Brands get caught in the middle. When a legitimate domain gets flagged and blacklisted, the business suffers immediate consequences. But the removal process is notoriously difficult:
- Which blocklist provider flagged you? You have to figure this out yourself.
- How do you contact them? Not always clear.
- What documentation do they require? Every provider is different.
- What is the process? Opaque at best.
- Will they respond? Some providers never do.
Businesses spend days or weeks trying to navigate this broken system while their operations are disrupted.
The solution is not better cleanup. It is prevention.
How Reputable Domains Works
The concept is straightforward: provide verified brand-domain data to the abuse ecosystem before problems happen.
Human Verification
When a brand submits their domains to Reputable Domains, we do not just run automated checks. Human reviewers verify every submission:
- Verify the brand-domain relationship through documentation
- Check business legitimacy and ownership
- Validate the domains are actively used for legitimate purposes
- Apply consistent verification standards across all submissions
This typically takes 24-48 hours, trading instant automation for thorough accuracy. Compare that to weeks spent fighting blacklist removals after the damage is done.
Distribution to the Ecosystem
Once verified, brand-domain associations are distributed through multiple channels:
REST API with sub-5ms average response times. Security teams can integrate verification checks directly into their workflows, whether that is abuse report generation systems, SIEM tools, or custom threat intelligence platforms.
CSV bulk downloads for organizations that need to import verified brands into their existing databases or blocklist systems. Perfect for abuse desks that process reports in batches.
AI agent integration for modern automation workflows. As AI becomes integral to threat analysis, verified brand data becomes a reference layer for intelligent decision-making.
The data flows to both sides of the abuse reporting ecosystem:
Producers can cross-reference before generating reports, avoiding false positives and protecting their accuracy.
Receivers can filter incoming reports, deprioritizing or auto-dismissing complaints about verified legitimate brands, allowing them to focus on actual threats.
Brands get proactive protection instead of reactive firefighting.
Who This Helps
For Brands: Insurance Against False Takedowns
If you manage domains, whether a handful or thousands, verification provides a layer of protection against being incorrectly flagged.
This is not a guarantee. We are transparent about that. Reputable Domains reduces the likelihood of false reporting and takedown, but it does not override security team judgment or prevent all possible issues.
What it does provide is verified data in the hands of the people who make blocking decisions. When your domain appears in abuse reports, decision-makers have additional context: this is a verified legitimate brand.
For companies with large domain portfolios, one verification process protects all your domains. Whether you manage 50 or 500+ domains, verify once and the protection applies to your entire portfolio.
The cascade effect is particularly challenging: when one domain gets blacklisted, automated systems often flag related domains showing similar patterns. What starts as a single issue spreads across your portfolio before you even know about the first flag.
The value is simple: 48 hours for verification once, versus days or weeks fighting blacklist issues reactively.
For Threat Intelligence Providers: Accuracy Enhancement
If you are in the threat intelligence business, accuracy is everything.
Maintaining accuracy at scale is challenging. Security teams face high volumes of alerts, and automated tools can generate false positives. Having verified brand data to cross-reference helps enhance accuracy and reduces the likelihood of reporting legitimate domains.
Reputable Domains gives you an additional data source to cross-reference before generating reports. It is not about catching fewer threats. It is about avoiding false accusations against verified legitimate brands.
This is especially valuable for automated detection systems where weak signals can trigger reports. Having verified brand data adds crucial context to your decision-making process.

For Abuse Desks: Free Filtering Tool
If you run an abuse desk at a registrar, hosting provider, or ISP, you know the overwhelming feeling of hundreds of reports flooding in daily.
Abuse desks face significant volume challenges with limited resources and the difficulty of distinguishing legitimate concerns from noise.
Reputable Domains offers free, unlimited access to verified brand data. Use it to:
- Filter incoming abuse reports by cross-referencing against verified brands
- Deprioritize or auto-dismiss reports about verified legitimate domains
- Focus your limited resources on actual threats that need investigation
- Reduce investigation time on reports that are obviously wrong
The API responds in under 5ms. The CSV downloads update regularly. There are no costs, no limits, no hidden fees. We built this to help improve the abuse ecosystem for everyone.

The Two-Sided Platform Model
The model is straightforward: brands pay for verification and protection, while security teams get free unlimited access to verified data.
More brands verified means more valuable data for security teams. More security teams using the data means stronger protection for brands. Better data quality across the ecosystem means fewer false positives for everyone.
Brands have immediate business motivation to prevent false takedowns: traffic stops, emails bounce, revenue losses mount. Security teams need better reference data but often lack budget for another tool.
Free access removes the barrier and drives adoption, making the prevention layer more effective for everyone.
Working Alongside Brand Protection Services
If you are familiar with brand protection services like PhishLabs, DomainTools, or Infoblox, you might wonder how Reputable Domains fits in the market.
We are not competing with those services. They focus on detecting and removing malicious domains that impersonate brands: finding the bad actors, gathering evidence, pursuing takedowns. That is critical work, and it complements what we do.
Reputable Domains focuses on the other side: verifying and whitelisting legitimate brand domains. We are providing the positive verification that security teams can reference when making decisions.
Think of it as two halves of the same equation:
- Brand protection services help you find and remove BAD domains
- Reputable Domains helps security teams identify and trust GOOD domains
Together, they give security teams more complete context for decision-making.
Built on Proven Infrastructure
Reputable Domains is not a prototype or beta experiment. It is production-ready infrastructure built by a team with deep domain industry experience.
Our founding team spent 8 years building and operating iQ Global's abuse management platform, serving 175+ registries and registrars and processing 250 million domains daily. We built Reputable Domains with the same production-grade approach: Go API delivering sub-5ms response times, PostgreSQL for data integrity, and enterprise billing through Stripe.
The Path Forward
We are starting with the foundation: human-verified brand-domain associations, distributed through modern integration methods (API, CSV, AI agent integration), accessible to both sides of the abuse reporting ecosystem.
We are committed to continuous enhancement based on user feedback, with early priorities including expanded portfolio management tools, automated alert systems, and deeper integration partnerships.
The vision is simple: make the internet safer by giving security teams better data to work with, and giving legitimate businesses protection from false flagging.
