G-Core Labs WAF is a robust and feature-rich web application firewall (WAF) that can detect and block malicious web traffic.

With increasing cybersecurity risks prevailing everywhere, technologies like WAF effectively keep attackers at bay.

But if you don’t use any security technologies, you can risk your website, applications, and network to attackers. As a result, you may lose your data and customer trust, enough to cause losses in terms of reputation and finances.

But if you use security technologies like G-Core Labs WAF, you can enhance your organization’s security posture and safeguard your data, network, and resources.

In this article, I’ll review G-Core Labs WAF and help you decide whether you should invest in it or not.

G-Core Labs WAF: An Overview

G-Core Labs WAF is a robust, modern solution to protect your web applications, website, and API from bots and Distributed Denial of Service (DDoS) attacks.

A leader in the CDN space, G-Core Labs is known for providing services with outstanding performance, functionality, and security at an affordable price.

As cybersecurity risks are growing each day, security solutions such as a web application firewall are necessary to ensure only legitimate traffic is allowed in and out of your web app and sites. It aims to provide security from unauthorized access and hacking of your data.

It’s not wise to block all the IP addresses, ports, and protocols because it would mean blocking legitimate traffic as well. Therefore, you need a quality protection system to analyze data packets and allow only those that are legitimate.

G-Core Labs’s WAF is excellent at it. It provides not only fully-fledged security but also useful features to enhance its functionality. Along with detecting and preventing attacks on web apps and sites in time, it also reduces the likelihood of attackers exploiting your vulnerabilities.  

Some of its customers are Avast, Redfox Games, TEDx, Sandbox Interactive, Bandai Namco, online retailers AWOK, Joom, etc.

G-Core Labs WAF: Features

Here are some of the features of G-Core Labs WAF:

L7 Protection

The application layer is at the top of the OSI model and is important since it interacts with the users.  And protection at this layer is also crucial because if an attack happens, it would risk your users’ data and application availability. It may disrupt the stable operation and cause your reputation to tarnish.

G-Core Labs WAF provides you with application layer (L7) protection from DDoS attacks. The attackers might try to render the responsiveness of your server by flooding it with an overwhelming number of requests than it can handle.

But with G-Core Labs WAF, you can deter these risks. It will neutralize attackers, even those that are of low frequencies on your websites and apps, which many other security solutions fail to detect.

NG-WAF by Wallarm

You will get WAllarm-powered NG-WAF to enable protection from manual hacking attempts to detect and exploit loopholes and vulnerabilities in your site without using a third-party SDK or performing code changes in your application.

Instead of getting into these complexities, leave everything to NG-WAF by Wallarm and stay relaxed, knowing your sites and APIs are safe.

Real-Time Bot Prevention

Attacks deploy malicious bots that crawl everywhere to find vulnerabilities and perform fraud. Using G-Core Labs WAF, you will get bot protection in real-time to prevent ad frauds, parsing, and data theft of your customers.

As a result, not only can you safeguard your systems and data but also uphold your customers’ trust in you and keep your head high in the industry.

Supports HTTP/2, Web Sockets, and IPv6

G-Core Labs support the latest protocols and technologies to increase security. Instead of supporting just the plain HTTP and IPv4, it supports the latest versions of HTTP/2 and IPv6.

It also supports web sockets to enable two-way interaction between the clients and the server – a full-duplex connection. It facilitates faster communication, performance optimization, and true concurrency to result in rich and responsive web apps.  

Supports HTTPS

Using HTTPS instead of HTTP offers more security to your website, applications, and API. You can do it by enabling an SSL certificate on your systems. There are many free and paid SSL certificates available that you can choose from.

Instead of HTTP offers more security to your website, applications, and API. You can do it by enabling an SSL certificate on your systems. There are many free and paid SSL certificates available that you can choose from.

But if you use G-Core Labs WAF, they support HTTPS and give you the option of whether you want to disclose the SSL certificates or not.  

As a result, your site and applications would be deemed safer, and people would love accessing it for their use.

Load Balancing

Load balancing helps distribute incoming web traffic among backend servers in a way that optimizes capacity utilization and speed. This also ensures no single server is overloaded with requests it can’t fulfill. An overworked server can exhibit poor performance and user experience.

This is why G-Core Labs WAF offers efficient load balancing, such as IP hash, Weighted Round Robin, and Round Robin. It will help ensure all your servers, including the main servers and backend servers, perform well and process requests. This will also help enhance the user experience.


You will get detailed statistics of everything going on in your application, site, or API security-wise. It will highlight the abnormalities detected by the WAF and blocked risk and attacks as well. This way, you can measure how well the WAF is working out for you and whether your investment is worth it or not.

IP Allowlists and Blocklists

G-Core Labs WAF supports IP blocklists and allowlists so that you can define who is allowed to access your application, API, and website and who can’t. If you detect some suspicious IP address wanting to break into your system, you can add them to the blocklists so that they can never enter your systems.

Similarly, you can create a list of IP addresses that are important to you and are genuine so that you can always permit them to access your site or app.  

API Security

G-Core Labs WAF protects your APIs from OWASP Top 10 security issues, credential stuffing, and API abuse. Hence, whether APIs you develop or use, you can secure its data and stay secure. 

In addition, you will get JSON-based API support, such as REST and CRUD, along with custom APIs. IT also supports custom XML-based APIs and XMLRPC. 

G-Core Labs WAF: How Does It Work?

G-Core Labs has a cloud platform with its own web traffic filtering centers located in Europe, the USA, and Asia.

Each of its nodes can process a minimum of several hundred Gbps of active web traffic, making the grand total of over dozens Tbps active traffic filtering. In addition, it has connected its nodes to various service providers across the globe who maintain backup copies of each of its systems and data. Hence, all the data housed in its managing servers, cleaning servers, network equipment, and data storage systems are perfectly safe.

Once you enroll with G-Core Labs WAF, you don’t need to protect your infrastructure yourself. They will do that for you so you can relax. They will ensure nothing can hinder your business processes. Even if something goes wrong for any reason, your customers and users won’t know about it since they will experience the same high-level performance.  

Let’s understand the steps by step process of how their unique security technology works.

Analyzing Resources

G-Core Labs WAF performs resource load analysis in real-time. It helps detect any statistical abnormality. Upon finding any issue at this point, it quickly blocks and keeps your systems secure.   

Technical Analysis

The WAF performs technical analysis of each new request received. It offers a deeper understanding of the data packets a client has sent and looks for any underlying issue that might be lurking.

Behavioral Factor Recognition

The WAF analyses the client’s behavior and who has sent the data packet. It begins if they have sent multiple queries within a given period during monitoring. It could be the time between a subquery and query.

Query Check

Next, the protection system checks the query against suspicious digital signatures relevant in real-time for the resource. The WAF checks the query for both proximity and coincidence cases.  

Query Validation

After performing all the checks and analyses, the protection system combines all the information into a one-factor vector. This calculates the validity of each query. As a result, the WAF will conclude whether or not the query must be given a pass into your network, system, or application.

If it passes the validation, the query will go inside your network and return the information asked. But if it doesn’t, the query will be blocked right away.

Furthermore, G-Core Labs WAF uses:

  • Proactive filter: It can block a majority of attacks and works with large traffic volumes. Its unsupervised training algorithms can reduce false positives.
  • Vulnerability detection system: It detects underlying security errors within your web apps. It also offers data about identified vulnerabilities and recommends eliminating those issues.
  • Virtual pathing system safeguards apps from security vulnerabilities by identifying and blocking threats and hackings in real-time. 

G-Core Labs WAF: Support

Customer support is an important factor if you choose any service provider. You may run into trouble at any time, and if you don’t know how to fix it, customer support will help you. 

G-Core Labs has knowledgeable and experienced engineers to help you when you need it. They are professional yet friendly to extend help no matter how complex your queries are.

In addition, you can refer to their knowledge base to seek answers to some common questions. 

G-Core Labs WAF: Use Cases

Here are some of the use cases where you can use G-Core Labs WAF.


The banking sector is heavily targeted by attackers. They may steal your databases with password and login combinations to access your systems. They can also hack accounts, acquire debit card and credit card information, and resell the data. Attackers can even conduct fraud with credits and coupons.

Hence, if you want to secure your data and systems, you need robust bank-grade technologies.

G-Core Labs comes to the rescue here. Banks can leverage G-Core Labs WAF to monitor singular requests, detect cyber threats, and mitigate attacks. It will block bots trying to access passwords and logins. 

Ad Networks

Malicious bots are everywhere on the web and are also spamming ad networks. They can hamper the credibility of ad networks, supply users with harmful ads and links, and trick them into revealing their information.

Using G-Core Labs, WAF will help detect risky traffic and automatically block the source generating ad impressions for bots. It will clean your paid web traffic and analyze low-quality sources to optimize your marketing budget.

Online Stores

Ecommerce businesses are also targeted by attackers since they attract a lot of visitors and, during sales times, are flooded with visitors. This increases the opportunities for attackers to flood the servers with illegitimate traffic and conduct attacks. They will also flood larger avenues to exploit user data at such times. Plus, without protection, parsers can freely collect data about your pricing and supply data to your competitors.

So, online stores can use G-Core Labs WAF to detect bot queries and block them. It helps provide reliable protection from attackers and competitors alike. It will also safeguard sales by closing manipulators using fake purchases.

Media Resources

Media resources like new channels, blogs, social media platforms, etc., are another favorite spot for attackers. They are always buzzing with users who visit those sites to seek information and entertainment. Articles, infographics, photos, comments, descriptions, etc., generate sales, boost search results, and improve the brand’s image. Hence, these must be protected from bots that copy these content pieces.

G-Core Labs WAF offers superior protection from attackers by analyzing traffic and preventing malicious bots from automatic copying. It also helps keep your site available all the time, even during DDoS attacks.
