With the most acceptable cloud firewall, protecting your web and mobile devices against unwanted access and hacking attempts is quick and straightforward. These are a crucial component of cybersecurity defenses on IT networks, serving as a ring-fence and guarding against harmful third-party assaults. Direct hacking, Distribution Denial of Service (DDoS) assaults, malware usage and stealing information, and other forms of direct hacking are all examples of these attacks.
While regular users may often use a firewall as a standalone program or a part of an antivirus software package, configuring a firewall for commercial apps can be significantly more difficult. However, there are several WAFs on the market, and in this article, you’ll examine some of the greatest ones right now.
What you will see here?
Cloudflare WAF
A firm called CloudFlare offers distributed domain name server providers, DDoS mitigation, Internet security, and content delivery services.
They will safeguard all online properties. CloudFlare’s protection is always active, thanks to ongoing upgrades.
Cloudflare handles a massive volume of requests every hour while simultaneously recognizing and blocking new threats. The platform may rely on collective intelligence to eliminate dangers because of its extensive consumer base. In other words, Cloudflare chooses whether a new WAF rule created by one client applies to all other domains on its network.
There is a free tier for Cloudflare. This includes worldwide CDN, shared SSL certificate, 3-page rules, and unmetered DDoS mitigation.
Akamai Kona Site Defender
First, the online app firewall of Akamai Kona Site Defender includes DDoS protection. DDoS services use a scale system from 1 to 10 to detect and eliminate threats from IP addresses. These ratings determine how well an IP address can identify questionable activity. Based on the severity of the score, scores are then utilized to allow, notify, or block. Additionally, users may change settings to specify which IP addresses they need to be blacklisted.
The web app firewall examines each piece of traffic separately. They halt any violent assaults. This program exclusively counters assaults launched over the web. Users may obtain data like reports and assault rates via the management dashboard. A minimal tweaking is necessary for the functionality.
Although, the free trial period and pricing may be started by contacting Akamai directly, which is how subscribers currently do so.
In a cloud solution dubbed Site Defender, Akamai, a global pioneer in DDoS mitigation, integrates complete DDoS protection with its web application firewall. A considerable advantage of merging these services into one security package is that you won’t have your traffic routed via two distinct organizations to have authentic requests coming to your web server.
Akamai frequently discovers new exploits first since it is a top internet security software provider. As a Site Defender user, you instantly gain from this “ahead of the curve” knowledge with tighter and more intelligent bans on hacker traffic.
Fortinet FortiWeb
Fortinet’s FortiWeb WAF is available as a SaaS solution, a VM-based software program, or an appliance. The WAF software may be a container-based system and accessible for private cloud hosting.
When used as an appliance or a cloud service, the FortiWeb system runs a DDoS prevention service. The web app firewall monitors every network traffic to identify suspicious activities and uses AI-based machine learning. To stay current on the most recent hacker attack tactics, FortiWeb additionally employs a threat intelligence feed. It searches for patterns of activity that depart from the calculated norm and appear to point towards a typical assault.
The cloud service has a monthly fee, and anyone with a standard browser can access the dashboard anywhere. There are eight variants of the network appliance version, with speeds ranging from 25 Mbps to 20 Gbps.
Imperva WAF
A cloud-based Web App Firewall is also available from Imperva (WAF). It offers app delivery together with content caching, load balancing, sophisticated bot protection, API security, web app security, and DDoS mitigation across a worldwide content delivery network.
All traffic entering your online services passes via the Imperva Web Application Firewall. It blocks harmful users and requests, including XSS and SQL injections.
A security staff looks after these. To safeguard its users, Imperva leverages network-based attack information. Imperva WAF maintains 24/7 surveillance thanks to its 45 DDoS-scrubbing data centers across the globe.
Other web-enhancement services, such as a content delivery network (CDN), which speeds up the flow of web pages and ensures constant availability if the primary server goes down for maintenance or sustains some sort of damage, are partnered with the Imperva Cloud WAF service. The WAF has a virtual patching service that updates the protected system with all necessary patches and maintains site access while the web server is being bounced.
For its Cloud WAF, Imperva offers a managed service option that comprises experts and technicians to administer the security program. Imperva WAF Gateway, a variety of network equipment, offers an on-site version of the Imperva security service.
Prophaze Web Application Firewall
A cloud-based proxy server called Prophaze WAF-as-a-Service serves as a web application firewall. The AI procedures in the Prophaze service improve detection rules by modifying the baseline of expected behavior. By lowering the frequency of false alerts, this function also opens actual site users’ access to the site.
The Prophase solution uses Kubernetes containers and can identify classic hacker behavior and monitor the efficiency and security of Kubernetes operations on your system.
The Prophaze WAF doesn’t require you to be an expert in utilizing it. The solution was created with non-technical users in mind because the company targets small enterprises using it. Any standard browser may view the dashboard’s displays, which are clear and well laid out.
DDoS defense and virtual patching are features. It strengthens the protected system and guards against data loss, assisting with GDPR, HIPAA, CCPA, PCI-DSS, and SOC2 compliance.
Signal Sciences WAF
Signal Sciences WAF operates in the cloud to apply managed and personalized rulesets to the traffic of your applications; Signal Sciences WAF is agentless. Along with security against botnet assaults, account takeovers, credential stuffing, API misuse, and DDoS mitigation, protections go beyond the OWASP Top 10.
The cloud engine from Signal Sciences, which handles roughly 200 billion requests every week, employs automatic blocking and scanning. In contrast to previous WAF systems, Signal Sciences SmartParse eliminates false positives through signature tailoring. 95 percent of their clients use Signal Sciences WAF in full blocking mode, which is excellent.
This offers real-time reporting, historical threat data, and reporting from the same platform without requiring third-party plugins or logins.
What is a firewall in the cloud?
Cloud firewalls regulate the information flow between external domains and your internal system like classic firewalls. These systems, also called “Next-Generation Firewalls,” combat today’s sophisticated attacks and safeguard the data used in your operation.
Does AWS have a firewall?
Client devices or your on-premises settings supported by AWS Transit Gateway are protected by AWS Network Firewall’s security measures for AWS Direct Connect and VPN traffic. AWS Network Firewall can limit this traffic to guarantee that only the least privileged access is given to VPC resources.
What are the 3 types of firewalls?
There are three different kinds of firewalls: hardware firewalls, software firewalls, or both.
Conclusion
These cloud firewalls are a barrier between a reliable internal network and a dubious exterior network (for instance, the internet). Cloud-based firewalls accomplish the same task by keeping an eye on online traffic and removing harmful requests by established security criteria. This prevents unauthorized access to private networks and cloud assets.
However, the Cloudflare WAF is the finest and has received excellent reviews. This has enhanced the ability to see how many people visit our websites. You can apply your own unique custom firewall rules that are better tailored to the sites in addition to the built-in WAF rules, which offer a high level of protection.
