Netlas
Tool Description: Internet intelligence and attack surface discovery platform to search and analyse publicly exposed infrastructure, domains, services, certificates, technologies etc.
Netlas
Quick Overview
What it does
Indexes vast amounts of internet-facing infrastructure and metadata, allowing users to search for domains, IPs, SSL certificates, open ports, technologies, services, login panels, APIs, and exposed systems.
How to use it
Search using keywords, domains, IP addresses, technologies, certificates, banners, or advanced filters. Results can reveal exposed infrastructure, linked assets, technologies in use, and potential security weaknesses.
Cost
Free for basic use. Paid for further functionality.
Account required
Yes.
Cookies
Yes - Security and bot protection, analytics tracking, storing user consent preferences, protecting authenticated sessions, and remembering interface settings
Ownership
Owned and operated by Armenian company Netlas LLC, headed up by CEO and co-founder, Arthur Kotylevskiy.
Use in Reporting
Useful to identify exposed infrastructure, correlate digital assets, and uncover publicly accessible technical data.
What does Netlas do?
Netlas acts like a specialised search engine for internet-connected systems. Instead of searching websites like a traditional search engine, it searches infrastructure data collected from internet-wide scans.
Users can search for:
Domains
IP addresses
Open ports
SSL/TLS certificates
Login panels
APIs
Technologies and frameworks
Cloud services
Email servers
Remote access systems
Exposed databases
Misconfigured services
It also supports advanced filtering and query operators, making it extremely useful for narrowing investigations quickly.
The lowdown: If you’ve used tools like Shodan or Censys before, Netlas sits comfortably in the same ecosystem, but with its own style, datasets, and querying strengths.
How to Use:
1. Search a company domain, IP address, ASN, technology name, or service banner.
2. Once you find a result, use linked metadata to expand the investigation. For example, you could explore other domains sharing the same IP, review SSL certificate details, or discover related subdomains or cloud assets.
Cost
A limited free tier is available, with premium plans unlocking larger datasets, historical scans, exports, API access, and advanced querying features.
Data Processing
Account Required:
Cookies:
Netlas uses cookies for security and bot protection, analytics tracking, storing user consent preferences, protecting authenticated sessions, and remembering interface settings such as theme preferences.
Use in Reporting
Netlas can provide strong supporting evidence in:
Threat intelligence reports
Exposure assessments
Red team reports
Infrastructure mapping
Incident response investigations
Vulnerability research
Attribution analysis
Security researchers use Netlas to discover what a company exposes to the internet (servers, subdomains, services, etc.), helping build a full digital footprint for reporting or audits. For example, it’s used to map infrastructure like web servers, email systems, and cloud services to understand exposure and misconfigurations.
Capabilities
Limitations
Internet-wide infrastructure discovery.
Advanced features are locked behind paid plans.
SSL certificate and domain correlation.
Data may not always reflect real-time changes.
Open port and service identification.
False positives can occur in scan results.
Technology and software fingerprinting.
Requires technical knowledge for effective use.
Advanced filtering and search operators.
Limited context around identified assets or services.
Attack surface and asset mapping.
Does not confirm vulnerabilities without further testing.
Summary
Netlas is especially valuable during cyber threat intelligence, attack surface mapping, and infrastructure attribution investigations. primarily sitting within the collection, discovery, and analysis stages of the OSINT workflow.
Ownership
Netlas.io is owned and operated by Netlas LLC, a company incorporated in Armenia since June 16, 2022. The cybersecurity search engine and platform are managed by a team led by CEO and co-founder Arthur Kotylevskiy, a cybersecurity expert.
Ethical Considerations
Avoid unauthorised access attempts.
Respect privacy and legal boundaries.
Verify findings before attribution.
Avoid active interaction with exposed systems unless authorised.
Consider operational security (OPSEC) when conducting sensitive investigations.
