• Cyber security has a heavy foot as IT explodes to new avenues such as BYOD and IoT, apart from cloud computing. Additionally, the speed at which technology changes makes threats evolve faster with cybercriminals finding new and creative ways to exploit users and technology all at same the time. Over the last few years, Cybercriminals have taken advantage of computer operating systems to silently deploy their malicious codes. In the old days, spam was the primary vector of delivery for malicious codes. But today, it has shifted to web based infections and browser based exploits that are recognized as clear perpetrator tools in this domain. Cyber security companies and security providers tend to exploit mitigations that could reduce the number of useful vulnerabilities. Another distinctive feature observed in this vertical is the attacks towards Internet of Things have been rephrased from proof-of-concept to mainstream risks. Without better security, attacks on technical infrastructure and devices are likely to have prominent negative real world impacts. The issue is of paramount importance that the security industry evolves to deal with these devices and vendors of such applications must grow to recognize the importance of security. Therefore, consumers continue to grow their awareness of the issue and thus, it becomes a commercial requirement, rather than being an afterthought or nag from security pros. Considering all causes and concerns of the subject, we present to you the top “20 most promising cyber security companies.” These security solution providers aid to rule out upcoming challenges and keep information off from cyber offenders. A distinguished panel comprising of CEOs, CIOs, industry analysts and CIOReview editorial team scrutinized various companies before finalizing the Top 20 names.
