Thousands of IT security experts use Netlas.io as a reliable source of information for their day-to-day operations

🙌 @netlas_io A valuable tool and a fantastic product that's making life easier for pentesters and bug hunters!

🐞🔍 With its advanced reconnaissance and automation features, Netlas is a game-changer for identifying security threats and vulnerabilities.

Today I tested @Netlas_io (since I needed a replacement for @securitytrails).
Its worth the money — some of you know I am heavily into automation, data quality is important. When it comes to price/performance ratio — Netlas is currently the way to go.
By aiding in the hunt for new cyber threats, they're not just providing a service, but fostering a community-driven approach to cybersecurity. Such partnerships amplify the importance of collective vigilance and shared knowledge in combating evolving digital threats.
Here is the best alternative to #shodan or #censys: @Netlas_io I got to know about it yesterday and it's really awesome.

Best-in-Class OSINT Apps

Tools for reconnaissance, non-intrusive security assessment, and security-related research

Non-intrusive Internet Scanner

Netlas.io scans every IPv4 address and crawls every known website and web application utilizing such protocols as HTTP, FTP, SMTP, POP3, IMAP, SMB/CIFS, SSH, Telnet, SQL and others. Collected data is enriched with additional info and available through Netlas.io Search tools.

Powerful Search Engine

There are five general data collections available right now: internet scan results, DNS registry, IP WHOIS, Domain WHOIS and SSL certificates. You can build search queries with different conditions and operators. Try to search using whois fields, GeoIP data, DNS registry data, protocol fields, technology and product names and even vulnerabilities.

Attack Surface Discovery tool

Start with a single domain or an IP address and build a complete attack surface for your target in a few clicks. Save it, share it, or download it as a list of targets for further scanning. Netlas.io Attack Surface Discovery tool is so easy to use and produces great results!

SSL certificates
Search any section of a host response
Search across the entire body of a web page. Use regular expressions. Detect almost any product or technology using the Netlas.io search engine.
Search by Favicon, Whois Fields, ASN and GeoIP data
Search and filter results using metadata such as a whois ORG field, emails, network names (ASN), hosting providers, a favicon hash and so on.
Search for Domains, Subdomains, Certificates and Technologies
In addition to its core Response search feature, Netlas.io provides additional DNS search and certificate search interfaces.
Handling of redirects
Unlike most competitors, Netlas.io scanners follow up to 5 HTTP redirects. Yes, we follow the white rabbit.
Vulnerabilities and PoCs
Netlas.io flags possibly vulnerable services and provides links to external tools that allow you to perform an active vulnerability assessment test.
API SDK for Python
Use Netlas.io on the web or through a CLI. Use the SDK to create automation scripts or to perform integrations with other products.

High Level of Data Coupling

Various pieces of information are already linked together to provide an extended context
Data mining is easier with Netlas.io. There are three main sources of information used for scan results enrichment. These are whois databases, DNS records and SSL certificates. Netlas.io provides interfaces for working with these sources directly and for working with already enriched scan results.

Complex Queries

Use wildcards, regexp, fuzzy & proximity searches
Netlas.io uses Elasticsearch as its general data storage engine. Search queries, whether they are entered using the API or the web interface, are transferred directly to the data storage engine with minimal preprocessing. Elastic's query string "mini-language" is very simple and flexible enough to create complex queries to find whatever data you need.

Queries with Protocol Fields

Queries that are more specific lead to results that are more accurate
Netlas.io search engine has advanced support of the most common network protocols. It means that host response fields are available as search query parameters. The mapping (fields available to search) consists of more than 10,000 fields. It's increasing continuously with each new protocol supported.

Please, take a moment to read through the help section of the application to understand the search capabilities.

Global Security Data

Cybersecurity research goes global with Netlas.io
The passive scan method used by Netlas.io identifies products and technologies from about 3 out of 4 host responses. In about a third of cases, the product version is also recognized. Vulnerabilities are identified based on product versions according to the U.S. Government National Vulnerability Database and updated with each new scan. Netlas.io also provides information about exploits availability.

Made for Automation

You can easily integrate Netlas.io in your own app
The Netlas web app uses an API that is available to any Netlas user. This means that you can call any function in the web app via the API from any third-party application.


Check out the Netlas Github repository. There you will find some Netlas usage examples and an SDK for the Python language. SDK implementations for other languages will come later.

The Netlas team welcomes the independent development of Netlas-based tools. These could be anything ranging from simple scripts to complex automation. Netlas API is available in the OpenAPI format.

Command-line Friendly

Use Netlas to orchestrate your needs. Utilize it in your automation scripts for data search and enrichment
The Netlas Python SDK includes a command-line interface. If you have Python installed, just use the Python package installer to setup the SDK. Once you have completed that step, you can interact with Netlas.io using the command-line.
