Benefits of AWS Shield for Your Business
Enhanced Security
AWS Shield significantly enhances the security of your applications by providing robust protection against DDoS attacks. These attacks can disrupt your online presence, leading to downtime, lost revenue, and a damaged reputation. With AWS Shield, you can ensure that your applications remain available and performant, leveraging AWS’s global infrastructure and threat intelligence to defend against a wide range of DDoS threats.
Improved Availability
AWS Shield helps improve the availability of your applications by automatically detecting and mitigating DDoS attacks. This always-on protection ensures that your services remain accessible to users, even during an attack. By minimising downtime and latency, Shield helps maintain a positive user experience and protects your business from the financial impact of service disruptions.
Cost Protection
DDoS attacks can lead to unexpected scaling charges as your infrastructure automatically scales to handle the increased traffic. AWS Shield Advanced provides cost protection by absorbing these charges, helping you manage your budget effectively. This financial protection ensures that your business is not burdened with unexpected costs during a DDoS attack.
Detailed Attack Insights
AWS Shield Advanced offers detailed diagnostics and reports on DDoS attacks, providing insights into the nature and impact of the threats. This information helps you understand the attack vectors and adjust your security measures accordingly. By gaining visibility into DDoS attacks, you can improve your overall security posture and better protect your applications.
