Web application firewall

Security is everything – robust protection for all your applications

Protecting your critical data and applications

Defending your data and applications has become more critical than ever. With businesses storing an ever-increasing volume of user data, it presents a lucrative target for cybercrime.

A web application firewall (WAF) is designed to ensure your data and applications are protected by blocking suspicious activity, providing comprehensive security for critical applications.

What is a Web Application Firewall (WAF)?

A Web Application Firewall (WAF) is designed to protect your data from hackers as they try to exploit weaknesses in your application code.

These targeted attacks are disguised as genuine requests made to forms on your site – to a traditional firewall or Intrusion Detection System/Intrusion Prevention System they will appear authentic and so allow them to proceed; making them either unable to guard against these attacks or unable to offer comprehensive protection.

WAFs are designed to proactively protect the application layer against attempted fraud or data theft; blocking any suspicious activity. Inspecting every web request for cross-site scripting, SQL injection, path traversal and 400+ other types of attack, this protective layer aims to keep your data secure.

Technical overview

Sitting directly on the application layer your WAF examines every HTTP request/conversation that comes through to your database server – and applies a set of bespoke rules set to filter out illegitimate traffic.

Custom rule sets are managed by security experts and exist for a wide range of applications. New rules can continually be applied to keep pace with new and emerging threats. Our WAF also proactively observes your genuine traffic, creating bespoke rules to ensure that any legitimate traffic is not blocked.

With no changes to your existing set up and an additional layer or protection, WAFs ensure that your site provides the upmost protection for your clients and also allows you to comply with PCI 6.6.

Our high-performance WAF solution is designed to safeguard against a number of vulnerabilities, including:

  • Cross-site scripting (XSS)
  • Injection flaws (SQL injection)
  • Malicious file execution
  • Insecure direct object reference
  • Cross-site request forgery (CSRF)
  • OS command injections
  • Information leakage
  • Improper error handling
  • Application denial of service
  • Broken authentication
  • Session management
  • Insecure cryptographic storage
  • Insecure communications
  • Failure to restrict URL access

Managed detection, response and SOC

Managed detection

Deploy next-generation endpoint and anti-virus protection, baseline hardening assessment, proactive attack prevention (e.g. brute force blocking), virus scanning, detection rule management, external vulnerability scanning, dashboards, metrics, reporting and alerting directly to you, the customer.

Managed response

Proactive 24×7/365 incident response to detected threats, external threat intelligence feeds to detect bad actors, monthly security reporting, vulnerability remediation, proactive threat prevention through SOAR playbooks and a glossary of use cases to protect businesses.

Managed security operations centre (SOC)

All data is fed directly into Azure Sentinel, benefit from event correlation from multiple data sources, with Artificial Intelligence & Machine Learning constantly updating and identifying ongoing attack patterns. Evolving security use case management to ensure new threats to businesses are detected, production of security orchestration, automation and response (SOAR) playbooks and rulesets, and built-in penetration testing throughout the contract lifecycle.
