By helping IT departments perform routine scans and detect flaws and unexpected changes in an organization's information systems, network security tools simplify network administration and monitoring and assist in auditing for security compliance purposes. Peripheral network security tools such as antivirus programs, firewalls, and intrusion detection systems work to keep networks safer. And, network security utilities like network mappers, port scanners, and packet analyzers, tools which are typically used in network penetration testing, allow administrators to identify the vulnerabilities hackers exploit in carrying out network attacks like DDoS and DNS spoofing.
The Disadvantages of On-Premise Network Security Tools
Although useful for troubleshooting and finding known vulnerabilities in network infrastructure, on-premise network security tools can be expensive, complicated and CPU-intensive, adversely affecting the performance of your company's servers and applications. Improper configuration can result in false positives, or worse, insufficient protection. Requiring time-consuming patching and updating and essentially limited in capacity and capabilities, network security tools cannot adapt to or maintain pace with the rapid evolution of today's threat landscape.
Moreover, automated vulnerability assessment tools are only capable of detecting documented flaws in your applications and configurations—not the weaknesses hackers will discover tomorrow. Intelligent vulnerability management, on the other hand, requires expert-driven manual penetration testing, which is costly and requires extensive planning, making it impractical for resource-constrained IT shops.
Web Security Made Simpler: Cloud-based Solutions from Akamai
Ultimately, many organizations will find that the ROI for traditional network security tools isn't quite what they expected, particularly when these defenses fail in the face of a large-scale attack. Fortunately, there is now a simpler, more cost-effective way for companies to achieve robust, scalable security for their servers, websites and applications—and spend less time and money on installing, configuring and managing on-premise network security tools.
With over 160,000 CDN servers in more than 95 countries handling over 5.5 Tbps of web traffic on average every day, Akamai offers our customers a globally distributed network of hardened servers and an in-depth, multi-layered approach to defense, providing:
- Flexibility. Built on the Akamai Intelligent Platform, our Cloud Security Solutions allow you to deploy the defense strategies most appropriate for each attack scenario and respond more efficiently and effectively to every type of threat.
- Scalability. Leveraging our platform's virtually unlimited capacity, our Kona Site Defender solution can absorb the massive amounts of traffic created by application-layer DDoS attacks while deflecting DDoS traffic targeted at the network layer.
- Performance. Our Web Application Firewall (WAF) filters out suspicious traffic in HTTP as close to the source as possible—without degrading the performance and availability of your websites and services—and can help to safeguard the SSL security of your applications.
