Global weekly cyber attacks increased by 8% in the second quarter of 2023, marking the most significant increase in two years.

As the number of cyber attacks rises, so do the costs. The global cost of cybercrime is expected to surge in the next five years, rising from $8.44 trillion in 2022 to $23.84 trillion by 2027.

Both the frequency and costs of cybercrime are expected to continue to rise as malicious actors use generative AI to create faster-paced, more effective, and larger scale cyber attacks

That’s why it’s more important than ever that organizations and individuals understand the importance of cybersecurity. This guide will provide an overview of cybersecurity, including what benefits it offers for organizations and individuals and how it works.

What is cybersecurity?

Cybersecurity refers to the efforts made to protect networks, systems, devices, and data from theft, damage, unauthorized access, and criminal use. It encompasses a broad range of measures, technologies, and practices designed to safeguard the confidentiality, integrity, and availability of information online. 

As cyber threats continue to evolve and become increasingly complex, cybersecurity has become a priority for individuals, organizations, and governments around the world. Let’s take a closer look at why cybersecurity is important below.

Why cybersecurity is important: 12 key benefits

Cybersecurity is important for safeguarding data, personal privacy, critical infrastructure, national security, and global security. Below we’ll take a closer look at several of these benefits, broadening the scope from why cybersecurity matters for individuals and the world. 

1. Protecting sensitive data

Many businesses, government agencies, and individuals store vast amounts of sensitive and confidential data electronically, including personal information, health records, intellectual property, trade secrets, and government secrets.

Implementing strong cybersecurity measures can help mitigate the risk of theft, exposure, or manipulation of this data by malicious actors.

2. Protecting personal privacy

Cybersecurity is also important for protecting data privacy. Data privacy is about empowering individuals to control how their personal data is processed, stored, and used by organizations and governments, while data security is about protecting that information from malicious actors. 

A cybersecurity strategy that includes privacy controls and measures can ultimately improve data security by limiting the amount of sensitive information that may be breached or exposed to unauthorized parties.

3. Preventing financial loss

Cyberattacks can lead to significant financial losses for both individuals and businesses. In 2022, an estimated 463 million individuals experienced a cyber crime. Over half of those individuals experienced financial loss as a result, at an average of $193 for US consumers. 

For businesses, the consequences of cyberattacks can be even more costly if they result in significant disruptions to their operations, lost customers and revenue, and regulatory fines. 

Take the 2013 attack on Yahoo, for example. When hackers stole data from three billion users’ accounts, the company had to notify all of its users that their data was compromised. As the biggest known breach of a company’s computer network, it made global news. After disclosing another incident that took place in 2014 and affected 500 million accounts, Yahoo almost lost its acquisition deal altogether with Verizon and ultimately, $350 million was cut from the original offer. Yahoo also suffered additional financial losses in numerous lawsuits, regulatory investigations, and scrutiny from governing authorities that precipitated the breaches. 

Investing in cybersecurity before a breach occurs can help avoid financial consequences like these.

4. Meeting compliance and legal obligations

Numerous laws and regulations, including HIPAA, PCI DSS, GDPR, CCPA, SOX, and FISMA, require organizations to safeguard sensitive data and protect the privacy of individuals. As mentioned above, failure to comply with these laws and regulations can result in penalties and fines. In addition to financial losses, organizations face other risks for failing to comply, including disruptions to their operations.

For example, non-compliance with PCI DSS could lead to the suspension of your ability to accept major credit cards like Visa and Mastercard. If you’re an ecommerce business, this could significantly impact your customers and revenue and even force you to suspend operations. 

Implementing a robust cybersecurity strategy can help organizations meet their compliance and legal obligations and avoid these compliance risks.

5. Ensuring business continuity

Cyberattacks, such as ransomware, can disrupt business operations, causing downtime and financial losses.

For example, a cybersecurity attack in August caused a wide-scale disruption of Clorox's operations, including order processing delays and significant product outages. The company announced that this disruption will likely impact first quarter earnings for 2024, and they expect sales to drop 23% to 28%.

Effective cybersecurity measures help ensure the continuity of operations and reduce the risk of downtime.

6. Building and maintaining trust

Trust is essential for businesses looking to accelerate growth. A data breach or security incident can erode trust with customers, partners, employees, investors, and other stakeholders and damage the brand’s reputation.

In a landmark study conducted by Ponemon Institute and sponsored by Centrify, 65% of consumers affected by one or more breaches said they lost trust in the breached organization and more than 31% said they discontinued their relationship with the organization as a result. 

This is a huge issue according to both CMOs and IT practitioners and. 61% of CMOs and 49% of IT practitioners in the Ponemon study said the biggest cost of a security incident is the loss of reputation and brand value. 

Implementing strong cybersecurity measures from the start can help you build and maintain trust with customers and other key stakeholders. 

7. Protecting shareholder value

Cybersecurity can also help protect the shareholder value of your company. In that same study by Ponemon Institute, they looked at the stock prices of 113 publicly traded benchmarked companies that experienced a data breach involving the loss of customer or consumer data, and compared what it was 30 days prior to the announcement of the data breach and 90 days following the data breach.

Their analysis showed that the companies’ share price declined soon after the incident was disclosed. However, companies that self-reported their security posture as superior and quickly responded to the breach event were able to recover their stock value after an average of 7 days, whereas companies that had a poor security posture at the time of the data breach and did not respond quickly to the incident experienced a stock price decline that lasted more than 90 days on average. The latter also experienced a 4% greater loss of share price than companies with a high security posture. 

Implementing a robust cybersecurity strategy can help reduce the risk of data breaches and consequent declines in your organization’s stock prices.  

8. Supporting national security

Governments and critical infrastructure are heavily reliant on digital technologies. Cyberattacks on national security systems can have devastating consequences on national security, public safety, and economic prosperity, impacting both public and private sectors. 

If threat actors are able to infiltrate government agencies, they may gain access to sensitive data, which potentially compromises classified information and exposes critical infrastructure. With this access, they may be able to destroy or alter data, impersonate legitimate people, and even degrade or disrupt federal computer networks.

For example, in the 2021 attack on the major US information technology firm SolarWinds, foreign attackers were able to use the hack to spy on US agencies, including the Department of Homeland Security and Treasury Department, as well as private companies, including Microsoft, Cisco, Intel, and Deloitte, and other organizations like the California Department of State Hospitals and Kent State University. Intelligence officers fear that these attackers not only gained access to sensitive and confidential information roaming around American computer networks for nine months, but also planted something more destructive for use in the future. 

Because cybersecurity is essential to the basic functioning of economies, the operation of critical infrastructure, the privacy of data and communications, and national defense, federal, state, and local agencies must implement enhanced cybersecurity measures to prevent attacks like the SolarWinds hack.

9. Defending critical infrastructure

As mentioned above, critical infrastructure such as factories, power grids, and water treatment facilities rely heavily on digital technologies. A cyberattack on these systems can have severe consequences for public safety and well-being.

A recent Waterfall Security report revealed that attacks that led to physical consequences in the real world impacted over 150 industrial operations in 2022, and that the number of these attacks more than doubled from 2021. Examples of the physical consequences of these attacks include: 

  • Outages at widely-known companies, including 14 of a top automobile manufacturing brand’s plants, 23 tire plants of a well-known brand, a major food company, and publishing company
  • Flight delays for tens of thousands of air travelers
  • Malfunctions of loading and unloading of cargo containers, fuel and bulk oil for half a dozen seaports on three continents

Cybersecurity measures can help protect the availability and resilience of this infrastructure and the essential services it provides.

10. Supporting global security

In today's interconnected world, cyberattacks can have far-reaching and cascading effects. A breach in one organization can impact partners, suppliers, and customers across the globe. 

For example, in 2017, Russian military hackers launched a ransomware attack known as NotPetya with Ukraine as its primary target. However, NotPetya quickly spread to more than 60 countries, destroying the computer systems of thousands of multinational companies, including the global transport and logistics giant Maersk, the pharmaceutical giant Merck, FedEx’s European subsidiary TNT Express, French construction company Saint-Gobain, food producer Mondelēz, and manufacturer Reckitt Benckiser, among others. With the total damage estimated at more than $10 billion, NotPetya is still considered the most destructive and costly cyberattack in history.

Cybersecurity is therefore essential for maintaining the stability of the digital ecosystem globally.

11. Reducing cybercrime

Defined as malicious cyber activity that threatens the public’s safety and national and economic security by the FBI, cybercrime is a global issue that affects individuals and organizations alike. 

As the NotPetya example above indicates, cybercrime is not only damage, destruction, or theft of data or money —  it is also the cascading effects that take place during and after the crime, including lost productivity, embezzlement, fraud, disruptions to the normal course of business, forensic investigation, restoration and deletion of hacked data and systems, reputational harm, and more.

Cybersecurity measures help protect both individuals and organizations from various forms of cybercrime, including identity theft, phishing, ransomware, and fraud.

12. Keeping pace with evolving threats

As technology advances, so do the capabilities of cyber attackers. Most recently, hackers are using generative AI to launch larger volumes of attacks. In a report by Deep Instinct, 75% of security professionals reported an increase in attacks over the past 12 months, with 85% attributing this rise to bad actors using generative AI.

Cyber attacks are not only more frequent but also more sophisticated thanks to AI. For example, hackers are using gen AI to create self-evolving malware, which automatically creates variations with unique techniques, payloads, and polymorphic code to attack a specific target and go undetected by existing security measures.

To stay ahead of malicious actors and new and evolving threats, such as AI-powered attacks, organizations must invest in ongoing cybersecurity measures and innovation.

How does cybersecurity work?

Cybersecurity works by implementing a broad range of measures and safeguards to protect networks, systems, devices, and data. Some of these are detailed below:

  • Access control: Access control is the practice of managing who has access to resources, such as data, files, networks, systems, or physical spaces, and what actions they can take with those resources. It is typically implemented through a combination of technical and administrative controls, including passwords, encryption, firewalls, and other security technologies to restrict access to resources and policies, procedures, training, and other measures to limit, control, and/or restrict manage access, monitor usage, and enforce security rules.
  • Baseline configurations: Baseline configuration refers to the most secure state a system can be in while meeting operational requirements and constraints like costs. This may include least functionality, segmentation, defense in depth or layers to limit the impact of risks. Developing secure baseline configurations is an important part of configuration management and cybersecurity overall. 
  • Security awareness and training: Human error can have serious consequences on cybersecurity. For example, consider that ​​ 73% of data breaches in 2023 involved the human element, either via error, privilege misuse, use of stolen credentials, or social engineering. Educating employees and individuals about security and privacy best practices is therefore essential to minimize the risk of cyber attacks within organizations and in their everyday lives. 
  • Security policies: Developing and enforcing security policies is essential for maintaining a strong cybersecurity posture. As mentioned above, these can help employees understand who has access to company systems as well as what other processes are in place to protect the organization and its assets and how they can behave to minimize risks. 
  • Incident response: Preparing for and responding to cybersecurity incidents, such as data breaches or malware infections, is a critical part of cybersecurity. Incident response plans outline instructions and procedures to detect, respond to, and limit the consequences of a security incident. 
  • Business continuity planning: Business continuity planning can help an organization identify preparations and recovery actions that can assist it in resuming operations and services as quickly as possible during and after a crisis. The document that contains the predetermined set of procedures that describe how an organization will sustain its business operations during and after a significant disruption is known as a business continuity plan.
  • Vulnerability management: Vulnerability management is a process organizations use to identify, analyze, and manage vulnerabilities within their operating environment. Vulnerabilities are weaknesses in systems, platforms, infrastructure, or even people and processes that can be exploited by threat actors, rendering an entire organization or any of its parts susceptible to attack. Having a robust vulnerability management process is an important part of an organization's overall security and compliance program.
  • Supply chain risk management: Supply chain risk management is a process companies use to manage supply chain risk. This involves identifying and assessing threats throughout the supply chain and developing mitigation strategies to protect the integrity, trustworthiness, and authenticity of products and services within that chain. This is an increasingly important part of cybersecurity as organizations’ supply chains become more global and complex, which means more potential failure points and higher levels of risk.
