Why Choosing the Right Cybersecurity Partner Matters
One data breach today costs companies an average of $4.45 million. Selecting the proper cybersecurity service provider is crucial to safeguard data, financial resources, and reputation. You require a cybersecurity partner with the expertise for:
- Penetration testing: Discovers vulnerabilities before hackers can exploit them.
- 24/7 threat monitoring: Guarantees in-real-time detection and response to cyber threats.
- Compliance assistance: Assists companies in addressing security requirements such as SOC2, ISO 27001, and GDPR.
- Not every web security company provides proactive, research-based security. AppSecure is unique in providing in-the-wild attack simulations, AI-powered threat detection, and customized security audits to keep businesses one step ahead of cyber attacks—not merely responding to them.
Conclusion
Cyber attacks are becoming sophisticated, making it better to choose the right cybersecurity partner. Businesses need more than security tools, much more important are the professionals who can find and remediate vulnerabilities before the attackers can.
It’s also not enough purely to react to threats. The act of simulating a real cyber attack will find vulnerabilities, proactively, before the bad actor will. Both pen testing and continuous app security scanning are required to get ahead of the inevitable attack.
Your business needs security professionals who can think like a hacker. Through bug bounty hackers and evidence-based security testing, Qualysec helps businesses of any scale to better protect their defenses.
