Top Computer Security Companies: How to Start Properly?

Computer security companies remain fundamental contributors to the concept of cybersecurity. The prime purpose for the emergence of such a company is the requirement to protect digital assets such as data and information systems from threats.

Computer security companies are those companies that specialize in offering a complete range of services, solutions, and expertise that are capable of securing and protecting computer systems as well as networks and data from destruction and attack. 

The main motive is to stop unauthorized access and breaches of data and to protect its clients from the attack. These companies indeed form the front line in the ever-changing and increasingly sophisticated threatscape.

Why Computer Security is a Necessity

With this age driven by computers, one truth remains: computer security is a much-needed thing. From business operations to government functions and even personal activities, virtually everything in modern life relies on computer systems and the Internet. This, therefore, exposes us to various cyber threats, including malware, phishing, ransomware, and so on.

That’s also where big help comes from computer security firms in such risk mitigation procedures that assure a high level of confidentiality, availability, and integrity of digital assets.

Computer security is an industry that has inculcated massive growth over time due to the ever-increasing threat of cybersecurity. The industry embodies a varied range of companies, from cybersecurity consulting firms to software developers, where each collectively and individually faces the aggregate work of facing cybersecurity problems on the global platform.

Historical Development of Computer Security Companies

Computer Security Companies: How to Start Properly?
Historical Development of Computer Security Companies

Given these considerations, I want to appreciate the historical development of computer security in general, which then led to the development of computer security companies through the years. The historical perspective would be most helpful in appreciating challenges and innovations developed in the industry.

  • Early Days of Computing (1940s-1950s)

The security of the computer started at a very early time when the mainframe computers had just come into use for scientific and military purposes. In its early times, security was brutish and leant to a large extent toward physical security in terms of locked rooms and highly restricted access.

  • 1970s:

The emergence of Main Primary Concepts for Computer Security: The roots of the main primary concepts for computer security, including the access control models or the design of password systems, started in the 1970s decade. Advanced security systems then started to form in this era.

  • 1980s:

The Computer Virus and the Antivirus Software: This was the first time in history when computer viruses were born, and hence, the need for antivirus solutions was being looked at. Companies like Symantec were the first ones to offer the solution in the form of antivirus software.

  • 1990s –

Internet boom, cybersecurity: With the dot-com boom of the 1990s, another challenge reared its ugly head: cybersecurity. The networks were in need of tools such as firewall technology and intrusion detection systems (IDS).

  • 2000s:

Growth of Cybersecurity: With the mounting complexity of the raising of threats over cyberspace, the industry for cybersecurity witnessed massive growth during the 2000s. Firms like McAfee and Trend Micro have gone ahead with an end-to-end security suite in the market.

Key Milestones in the History of Computer Security

  • 1988: Morris Worm: The Morris Worm is one of the early internet worms that brought along some serious issues pertaining to poor network security systems. It was estimated to have infected over a thousand computers, and in response, led to the formation of the Computer Emergency Response Team (CERT).
  • 2002: Sarbanes-Oxley Act: Regulatory compliance and cybersecurity came under tremendous focus for the Sarbanes-Oxley Act of the year with its policies on data protection and the reporting requirements that are expected of public companies.
  • 2010s: A Rise in Advanced Persistent Threats: The evolution of the decade since 2010 was marked by the advent of the proliferation of Advanced Persistent Threats (APTs) in a sophisticated manner, with targeted attacks from nation-states and cybercriminals. They needed the use of advanced solutions to detect and react to such threats.
  • COVID-19 and Remote Work: The landscape of remote work further escalated with the advent of the COVID-19 pandemic and hence presented a wider attack surface. In most cases, cyber attackers have taken advantage of this shift in working arrangements to successfully create increasing numbers of phishing attacks, ransomware incidents, and other types of cyber threats to organizations’ remote workers.

Advanced Threats and Nation-State Actors

The advanced cyber threats of the last decade comprising activities of nation-state actors had shown a peak in the sphere. These threats included espionage campaigns, supply chain attacks, and disruptive cyber attacks on critical infrastructures that were indeed very serious in nature, thereby portraying an apparent need for strong support in cybersecurity assistance through threat intelligence.

In modern cybersecurity, there are components of Artificial Intelligence (AI) and Machine Learning (ML). AI and ML are used in identifying threats, anomalies, and behaviors so that actions are taken in a more proactive and flexible manner in the security domains. More importantly, there is a bigger outlay by organizations on AI-based security solutions that can preempt the emerging threat.

Zero Trust Security: Zero Trust is one of the brand new buzzwords in designing for security within the 2020s. It implies that no entity, whether inside or outside the network, is to be trusted by default. Zero Trust architecture hinges on identity and access management, continuous authentication, and strict access controls.

Cloud security: It has also brought in relatively new challenges in the space. Cloud security companies are the companies that offer specific tools or services to protect data and applications in the cloud. Identity and access management (IAM) and cloud workload protection platforms (CWPP) are some of the key focus areas.

DevSecOps for Secure Development of Software: With DevSecOps coming into play, it makes way to bring in security by default in the DevOps pipeline. Such offerings in the form of security by security companies now cater to the need for security testing, a scan for vulnerabilities in an automated manner, and also analysis of code so that it fits the definition of being secure by design.

Regulatory and Compliance Landscape: Goverjsoning bodies and governments force strict guidelines over data protection—European Union GDPR, California Consumer Privacy Act (CCPA), and many others. It is amply evident that all these evolving requirements keep making compliance management and data privacy solutions high in demand.

Cyber Security Skills Shortage: Truly, the past few years have seen a decade that really underscored a huge shortage of skilled professionals in cybersecurity. The challenge has always been there, if not a worry, for organizations to really find and retain highly qualified talents that drive them to invest further in managed security service providers (MSSPs) and automation.

Ransomware and Extortion: Increasingly, in many ransomware attacks, threat actors target more critical infrastructures in a more focused fashion and often make use of double extortion tactics. Advanced Anti-Ransomware Solutions.

Global Collaboration and Threat Sharing: As the nature of cyber threats continues to grow in number and complexity, the need for global collaboration among governments, law enforcement agencies, and private sector organizations has also emerged. Sharing of intelligence and collaborative efforts on the means of cyberspace defence.

This was, indeed, a completely new era of cybersecurity in the 2020s. With their services and technologies constantly updated and robust in an apparent race against time, this is how cybersecurity companies try to shield organizations and individuals from an increasing variety of cyber threats.
