Most Popular Cybersecurity APIs for 2020

by Mic Johnson

The latest technology has turned the world upside down, and of course, for good reasons. Speaking of Application Programming Interfaces, API – it is a standard method of improving, integrating, and sharing data through online services.

API services have entirely changed and evolved how the digital world works. From digital coins to payment wallets to e-commerce websites, and social networks – APIs are available for anything. Moreover, there are two teams of APIs – the red team and blue team – which are responsible for boosting the cybersecurity market. 

Following are the best API services available for cybersecurity in 2020. 

Google Safe Browsing API 

Safe Browsing is Google’s highly respected cybersecurity program that helps protect users from accessing phishing domains, challenging sites, and web pages infected with malware/virus.

You can automatically test pages against the Safe Browsing database by using the Safe Browsing API, allowing you to detect the type of threat affecting a Web page. This is useful to warn users before moving on to any dangerous website and to avoid the sharing of infected links within your own company.


Lookup API – It is useful for instantly checking the status of a URL

Update API – It permits client apps to download Safe Browsing lists for local client-side URL checks

Local Databases – It enables downloading and using local URL databases in initial checking.  

Caching – A useful tool to prevent unwanted questions and to speed up your final response to requests from clients.

Compression – It lets you reserve bandwidth while generating queries against the SafeBrowsing API. 

Metadata – It helps in identifying threat types. It also allows to set up several forms of edifying warnings whenever a malicious URL is found. 

Quttera API 

Quttera is among the most popular malware scanners online around the world. This offers a simpler and faster way of finding out whether your website is infected with random malware or viruses. 

Using their API, you can integrate their powerful ability to scan and monitor malware into your application layer.


  • Full-in-depth scan results 
  • Proactive monitoring and scanning 
  • Run and hosted in the Cloud
  • Ability to check for other sites URL in the Quttera database 
  • Built-in multithreading for faster scan speed
  • Integrations: REST API returning XML, JSON, and YAML based-responses 

GreyNoise API

We had published a candid and insightful interview with Andrew Morris a few weeks ago, the mind behind GreyNoise Intellect. Today we are excited to tell you more about the purpose of the business.

Security researchers, as well as private and public entities, use GreyNoise to analyze security-related data from the Internet. The system, developed by Morris himself, specializes in collecting and analyzing data from several scanners, including Shodan.io, and placed above several data centres in the world by their own network scanners.

Cloudflare API 

Bearing in mind Cloudflare’s tremendous influence on the cybersecurity sector, it is difficult to build a list of cybersecurity APIs without including theirs. As you might be aware, Cloudflare is a proxy-based service that allows you to improve your company’s site efficiency and device protection by simply altering your domain name servers.

Domain and DNS protection, SSL encryption, VPN for Chrome and successful anti-DDOS solutions concentrate on powerful high-end DNS and web application firewalls (WAF).

The __cfduid cookie is used to identify individual clients behind a shared IP address and apply security settings on a per-client basis.

cookie_notice_accepted and gdpr[allowed_cookies] are used to identify the choices made from the user regarding cookie consent.

For example, if a visitor is in a coffee shop where there may be several infected machines, but the specific visitor's machine is trusted (for example, because they completed a challenge within your Challenge Passage period), the cookie allows Cloudflare to identify that client and not challenge them again. It does not correspond to any user ID in your web application, and does not store any personally identifiable information.

The _ga is asssociated with Google Universal Analytics - which is a significant update to Google's more commonly used analytics service. This cookie is used to distinguish unique users by assigning a randomly generated number as a client identifier. It is included in each page request in a site and used to calculate visitor, session and campaign data for the sites analytics reports. By default it is set to expire after 2 years, although this is customisable by website owners.

The _gat global object is used to create and retrieve tracker objects, from which all other methods are invoked. Therefore the methods in this list should be run only off a tracker object created using the _gat global variable. All other methods should be called using the _gaq global object for asynchronous tracking.

_gid works as a user navigates between web pages, they can use the gtag.js tagging library to record information about the page the user has seen (for example, the page's URL) in Google Analytics. The gtag.js tagging library uses HTTP Cookies to "remember" the user's previous interactions with the web pages.
