Top 10 Cybersecurity Best Practices in 2025

Organizations are vulnerable to the most common cyber attack vectors, and the numbers agree since cyberattacks rose 30% since 2022. ¹

Companies need to improve their cybersecurity risk management posture before they lose money and reputation due to a successful breach. See the top 10 cybersecurity best practices for businesses to improve their firms’ cybersecurity posture and build strong network security.

1. Adopt suitable technology to reach zero trust principles

Some technologies support a zero-trust mentality. Companies can deploy the following technologies to improve their cybersecurity posture: 

• Data loss prevention: With the rising number of data breaches, employing automated Data Loss Prevention or DLP software has become crucial for protecting your business’s sensitive information. Additionally, automated DLP systems can significantly reduce the workload on IT departments by efficiently monitoring, detecting, and responding to potential threats without constant human oversight.
• Secure access service edge: SASE is the unified network and security solution for organizations that have network and security components together. SASE’s network as a service component includes  SD-WAN, carriers, content distribution networks, and edge devices. Security as service components include firewall as a service, ZTNA, and SWG.
• Zero trust network access: ZTNA is a cybersecurity solution that constantly verifies users and devices to permit access.
• Secure web gateway: SWG provides protection against internet-based cyber threats thanks to functions like URL filtering and malicious code detection. 
• Software defined perimeter: SDP software is the new generation network cloaking tool. Unlike VPN, it allows microsegmentation and ensures the least access privilege. 
• Firewall audits: Automated firewall audit software can enhance a company’s network security by systematically identifying and rectifying configuration errors and vulnerabilities.

2. Prepare board and C-level leaders

Without board and C-level leadership buy-in and oversight, it is almost always impossible for firms to transform. The cybersecurity posture of a company is not an exception. The board  needs  to demonstrate a high maturity about cybersecurity concerns where they have at least basic knowledge about:

• Cost of cyber threats.
• Types of cyber attacks.
• Industry-related cyber weaknesses.
• Compliance measures.
• Recent cybersecurity posture of the company.
• Available technologies.

In a company that has an effective organizational structure, board and C-level leaders should have the following duties:

• C-level cybersecurity leaders: The board must appoint a C-level leader, such as a chief information security officer (CISO), to be responsible for the company’s cybersecurity management. This person should be knowledgeable about both the business and technological aspects of the issue.
• Regular cybersecurity meetings: Cyberattacks and their results must be regularly shared with the board.
• Board-departments collaboration: The company’s cybersecurity policy must be disclosed to the board. Departments and boards of directors must work up a budget for system maintenance and new technology investment. However, almost 70% of companies do not take such actions. ²
• Third-party assurance: Firms must work with third parties to ensure their progress.
• Targeting international certificates: Board must consider having international certifications like ISO 27001 or HIPAA that represent data compliance of companies. Targeting such certificates help firms to improve their cybersecurity posture.

3. Assess your cybersecurity posture

Prioritization is critical for introducing a successful transformation plan. Begin by:

• Identifying high-risk assets: Determine if attackers are more likely to target employee personal data, customer databases, or intellectual property.
• Reviewing regulatory requirements: Consider the impact of industry-specific laws and recent mandates—like immediate breach reporting for vital sectors.
• Conducting risk assessments: Identify weak points in your current cybersecurity measures and address them systematically.

After finding these weak points, you can search for ways that mitigate these risks.

4. Enhance employee cybersecurity awareness

Almost half³ of the business leaders think personal mistakes are the primary cause of a data leak at their company. The rise of remote/hybrid working expands the scope of employee-caused data breaches, as mobile workers frequently use insecure computers and Wi-Fi networks, making them easy targets for hackers.

Therefore, educating employees regarding the following issues is an important cybersecurity best practice: 

• Pop-ups, unknown emails, and links: Phishing and hacking people by sending some links or pop-ups are frequent types of cyberattacks. Fraudsters try to steal information from employees by sending them official-looking emails. Employees of all levels should receive regular cybersecurity awareness training to help them become better at recognizing phishing emails, fake websites, bogus, and other signs of fraud.  
• Passwords: Fraudsters have sophisticated methods for cracking passwords, and it is relatively simple for them to do so, especially if your password contains your name or date of birth. A password should be at least 12 characters long and have a combination of numbers, symbols, and upper- and lower-case letters. Firms should, however, utilize multi-factor authentication for added protection, as we outline in best practices #4.
• Wi-Fi security: Cybercriminals can utilize wireless sniffing software to reach data and transactions when employees use public access points that are not secured. Thus, employees should not use public Wi-Fi, especially when they work with sensitive data.
• Software updates and patches: Only 43% ⁴ of corporations have a commitment of installing software upgrades within 14 days. On the other hand, businesses can protect themselves against cyber dangers by updating software. Thus, they should educate their employees on the need for updating.
• Regular virus monitoring: Employees often use their own laptops or devices due to remote/hybrid working. However, they might not have antivirus programs or they might not use them regularly. Thus malware software can cause data breaches.

5. Implement zero trust cybersecurity model

According to the zero trust cybersecurity paradigm, potential users, devices, and network  systems are always verified to gain access to documents. Thus, it is a suitable cybersecurity best practice in today’s hybrid/remote working practices where the device and network security is ambiguous. 

• Introduce multi-factor authentication: Cyber attacks often use hacked accounts to gain access to a firm’s internal resources. Multi-factor authentication makes it difficult for hackers to access corporate data.
• Validating devices: Device identity and security, in addition to user identification, should be validated systematically.
• Minimize data access: Allowing employees access to as little data as they need to complete tasks (least access privilege) reduces the attack surface and, thus, the cost of successful breaches.
• Adopt micro-segmentation: To prevent computer viruses from spreading quickly (lateral movement), data should be stored in numerous micro-segments. 

6. Conduct API security testing 

90% ⁵ of developers rely on APIs to enhance their services efficiency and customer friendliness; however, only 11% ⁶ of businesses have an API security plan that covers testing APIs in its entirety. That is why it is not surprising that 95% ⁷ of APIs experienced security exploits.

API security testing can:

• Protect from external attacks.
• Identify security flaws in the code before API deployment.
• Comply with security regulations.
• Report potential risks to the API in real-time.

7. Leverage white hat hackers

Measurements are always necessary to assess the performance of your measures. Therefore, it is logical to employ white hat hackers who examine your cybersecurity without causing any data leakages.

White hat hackers (also known as ethical hackers) utilize their hacking expertise to find security flaws in infrastructure, software, and networks. White hat hackers do not violate the law and do not cause data breaches, unlike black hat hackers. 

To examine the performance of your cybersecurity posture, white hat hackers use the following methods:

• Email phishing.
• Denial-of-service (DoS) attack.
• Pen testing.
• Implement social tests within the company to assess workers’ weaknesses.

8. Implement audit trails in your digital operations 

Audit trails are used to bring robustness to operations in cases such as:

• Lowering the risk of fraud
• Preventing significant errors in financial statements
• Preventing unauthorized users from accessing company resources
• Assisting businesses in identifying attempts at asset theft

Similarly, they are useful in cybersecurity in providing the data to figure out how security incidents happen.

The key to responding to unanticipated situations quickly is a timely investigation of the behaviours or movements of your staff, privileged users, or third-party vendors. An audit trail can benefit your company by:

• Enhance the responsiveness to incidents by preparing security teams to learn from past incidents to better prepare for future security incidents by reconstructing events via audit trail analysis 
• Aiding security personnel in spotting instances where hackers attempt to breach networks and do harm.
• Detecting cyberattackers’ previously hidden activity 
• Preventing negative actions like system abuse and internal fraud

9. Back up your critical data

At its core, cybersecurity management is concerned with minimizing the reputational and financial consequences of cyberattacks. Consequently, businesses should consider not only preventing data breaches but also minimizing the cost of successful breaches.

Ransomware assaults, which seize business data and release it in exchange for a random amount of money, more than doubled.⁸ If the leaked documents are critical to the company’s core activities, the corporation becomes heavily dependent on hackers. As a result, routinely versioning key data and keeping it in a separate location (hardware, for example) might help businesses stay operational following a ransomware attack.

10. Invest in cybersecurity insurance

As we digitize, new risks, such as cybersecurity risks, emerge. Thus, the insurance sector finds new instruments that reduce an entity’s risks. Cybersecurity insurance minimizes the damages of cyberattacks. As of the beginning of 2022, almost 70% ⁹ of companies use such policies.  

Cybersecurity insurance provides coverage for the following scenarios:

• Privacy liability coverage: Covers against legal costs and penalties
• Network business interruption cost: Covers expenses during a period when they are unable to function as a result of a cyberattack. 
• Media liability coverage: Covers reputational costs of cyberattacks.
