15 Cyber Security Best Practices for your Organisation

As per Statista, the cost of cyber attacks will hit 10.5 trillion in 2025 as they continue to grow in complexity and volume. Amidst such an increasingly challenging environment, cybersecurity best practices that were adequate a few years ago will now be outdated in 2025, leaving companies that aren’t prepared defenseless. The message is clear—a massive overhaul is needed, and that is exactly what we discuss in this blog. 

We spoke to CEOs, Founders, and Business Heads from companies across industries to understand the cybersecurity best practices they recommend for organizations in 2025. 

Let’s dive in:

What is cybersecurity?

Cybersecurity is building resilience against cyber attacks through processes, policies, company culture, and technical safeguards. The overarching goal is to preserve organizations’ critical assets’ confidentiality, integrity, and availability to reduce the risk of fines, business disruption, financial losses, or reputational damage. 

Importance of cybersecurity

In today’s age, where businesses operate in cloud environments, data breaches and cyber-attacks are not just potential risks but inevitable events that can occur to any business at any moment. The potential implications of a compromise are huge for an organization, as it might compromise sensitive data like customer information, banking details, and more. Moreover, with advancements in AI accelerating the volume and sophistication of threats such as phishing, the a need for robust measures that not only prevent threats from snowballing into incidents but also contain the impact of breaches when they occur. Thus, strong cybersecurity practices are essential, providing a critical layer of assurance against the disruptions these threats can pose to business operations.

1. Empower Employees to Thwart Hackers

“No matter how secure your cloud infrastructure is, one weak link will always be there: your employees. Unless they are aware of the threats that exist, they will never be properly equipped to fight them. 

Therefore, my 2023 resolution for maintaining my organization’s cybersecurity posture is to train my employees to be cyber ninjas. Employees are often the first line of defense with cyber-attacks.

Moreover, cybersecurity is not just a headache for the IT department; it affects everyone. Every single employee has a role to play in protecting their organization’s assets.

No amount of monitoring will save your assets unless the employees understand their responsibility. 

Cyber attacks are getting more and more sophisticated, and 2023 won’t be any different. Social engineering is also easier now that people can take help from AI tools like ChatGPT. As cybersecurity is a growing concern, it is more important than ever for employees to understand its importance.”

Andreas Grant, Founder, Networks Hardware

2. Include Cybersecurity Teams in All High-Level Meetings

“In 2023, I want to ensure that we include our cybersecurity team in all high-level meetings regarding the company’s security overall. In the past, these meetings would often only involve the CEO, myself, and a few other board members.

However, as time goes on and security threats become more palpable, organizations must prepare for anything that might come their way. 

Including the cybersecurity team in these meetings seems to make the most sense. Their experience, insight, and input can help us make better, more secure decisions in the future with how we interact with technology.”

Dustin Ray, Co-CEO & Chief Growth Officer, Incfile

3. Use a Multi-Factor User Authentication Function

“We will implement user authentication across all systems to protect data from attackers because of weak passwords. Multi-factor authentication for online systems access will help prove digital identities to enhance authorized access only to the organization’s data. 

Focusing on the data protection fundamentals such as multi-factor user authentication will help the organization stand firm in data security to prevent instances of phishing and unauthorized access.

The organization will also conduct training and awareness campaigns among the employees to emphasize the areas of data attacks and how to avoid them.”

Yongming Song, CEO, Live Poll For Slides

4. Complete Log Outs

“Something I’m totally guilty of, as well as most of my employees, is staying logged into accounts and devices after I’ve left them. This is the exact opportunity hackers look for when trying to gain access. 

If you’re already logged in to an account, and a device or profile falls into the hands of a hacker, you’ve made their job insanely easy! There’s no password-busting or firewalls in their way—they’re already in. 

That’s why my resolution for 2023 is to completely log out of every device after I’m done with it. Every time. And the same goes for our employees.

This is a company-wide update for the New Year, and I plan to implement timed logouts wherever possible on all devices and accounts.”

John Ross, CEO, Test Prep Insight

5. Train to Spot and Prevent Cyber Attacks

“As part of my 2023 resolution, we plan to train all employees on cybersecurity regularly. This training will include identifying phishing and other social engineering attacks, knowing what types of data are sensitive and should be kept secure, how to spot a potential data breach, and how to report any suspicious activity to management. 

We want to ensure that our employees are trained on how to use the cybersecurity tools and technologies provided by the organization, such as firewalls and intrusion detection systems, so they can spot malware, ransomware, and other forms of malicious software on time that could compromise our systems.”

Arkadiusz Terpilowski, Head of Growth & Co-Founder, Primetric

6. Consolidate Vendors to Minimize Risk

“Scheduling regular cloud audits and consolidating software licenses around single vendors are proactive measures to minimize the risk of a cyberattack.

Cyberattacks are becoming more prevalent as the global economy is in flux. So, it’s crucial to review your company’s tech stack before thieves get a hold of sensitive data. 

Because a business without digital protection can quickly grind to a halt when an attack hits, and playing catch-up can be lengthy and costly. But conducting cloud audits and minimizing software licenses reduces the number of entryways thieves can try to access. 

Although this takes time and effort, the additional security is worth it these days. It enhances consumer confidence in purchasing from your brand online and encourages them to continue doing business with you.”

7. Have More Partnerships to Fill Security Gaps

“Not every company needs to be an expert at everything. For highly-specialized areas such as cybersecurity, it often makes more sense for companies to invest in a service than to hire and train an internal resource. 

With cybersecurity monitoring, response, and remediation becoming a more recurring necessity than a one-time assess-and-fix—the approach and services required have shifted as well.

Some level of managed security services has become critical for mid-size and enterprise companies and is becoming more and more important for small businesses as well. 

Cybersecurity in 2023 should center on identifying any holes in current security measures and selecting partners to help shore up the gaps. Look to managed detection and response services, vulnerability management services, and security awareness training, among others.”

Colton De Vos, Marketing Specialist, Resolute Technology Solutions

8. Prepare an Incident Response Plan

“In 2023, we will prepare an incident response plan in the event of a breach. Just like a business needs a fire escape plan if the office building is on fire, an incident response plan will help navigate data breaches. 

We’ll assign a few of our cybersecurity employees a role in an incident response team. They’ll be first on the scene when there’s a data hack, trying to contain the situation.

We’ll also outline standard investigation procedures and processes, so everyone knows their responsibility in a breach.”

Scott Lieberman, Owner, Touchdown Money

9. Adopt Zero-Trust Security Principles 

“My goal for 2023 is to follow the zero-trust security concept. Neglecting cybersecurity precautions could prove to be the worst decision of any organization.

The phrase “zero trust” refers to the practice of always authenticating and authorizing users based on all available data, such as user identification, location, device health, service or workload, data classification, and anomalies. 

This is the best course of action to take in order to be cautious about cybersecurity issues that could jeopardize the organization’s overall security.

The regular occurrence of security breaches at well-known tech organizations around the world also justifies the inclusion of this resolution on the priority list.”

Sean Harris, Managing Editor, Family Destinations Guide

10. Update Passwords Each Quarter

“My 2023 resolution is to reevaluate, update, and strengthen our passwords every quarter. We often take password security for granted as something that only needs to be done once, but data shows this is not enough. 

Setting the expectation of regularly refreshing passwords can help protect my organization’s intellectual property, customer information, and confidential files. I plan on instilling a quarterly password change policy that will work with other necessary security protocols to safeguard our online presence.”

Ludovic Chung-Sao, Lead Engineer & Founder, Zen Soundproof

11. Strengthen the Internal Team

“The best way to maintain and improve my organization’s cybersecurity is to build a strong internal team that works together with outsourced professionals. This approach will ensure that the resources and continuum of expertise needed to help secure our IT environment are available. 

With this strategy in place, we can benefit from the guidance of security professionals while also strengthening our abilities to address potential issues quickly and effectively.

It is also important that any changes made will be integrated into our systems correctly and without sacrificing security measures or data integrity valued by our organization.” 

Therefore, as I meet my cybersecurity goals for the coming year, building a robust team with internal experts and contracted support will be my top priority.”

Derek Bruce, Sr. Director, Skills Training Group

12. Take advantage of AI

“Artificial intelligence has proven to be impactful in almost every industry segment, and in 2023, it only makes sense to leverage its advantages in cybersecurity, too.

While the ability of AI tools and platforms to keep learning from their environment proves to be highly impactful in a cyber world that is growing every minute, another advantage these tools offer is sped-up response times. 

With real-time reactions that keep security threats at bay and enhanced vulnerability management that quickly secures networks, we have every reason to include AI solutions in our cybersecurity roadmap for 2023.”

Brendan McGreevy, Head of Strategy, Affinda

13. Use a Software Assurance Maturity Model

While compliance does provide a baseline of security, it doesn’t guarantee it. And so, Software Assurance Maturity Model (SAMM) serves as a valuable tool to improve software security practices for better risk management.

Developed by an open community, OWASP, SAMM provides a set of best practices for assessing the current levels of security maturity and for further enhancement.

“OWASP SAMM helps focus our resources and determine which components of a secure application development program should be prioritized”.

Michael J. Craigue, Information Security & Compliance, Dell, Inc.

14. Conduct Due-Diligence and Research Software Vendors

“I plan to invest in software that is transparent about its cybersecurity precautions and use monitoring tools to detect any security breaches at these third parties. I will also research the software’s security policies and ensure they are up-to-date and compliant with industry standards.

Additionally, I will use monitoring tools to detect suspicious activity and alert me to potential security breaches. I also plan to use third-party vendors to provide proof of their security measures, such as penetration testing and vulnerability scans.” 

Tasia Duske, CEO, Museum Hack

15. Stay Up-to-Date With the Latest Security Trends

“Cybersecurity is an ever-developing field, and keeping up with the latest trends and threats can seem daunting. It’s important to stay informed and ensure your organization is prepared for potential threats. 

To do this, we seek to invest in security solutions that provide real-time monitoring and threat intelligence to help identify vulnerabilities and enable proactive measures.

Additionally, it’s important to keep up with emerging malware or ransomware threats so that appropriate safeguards can be implemented. 

That’s why we plan to create a culture of awareness and training around cybersecurity best practices, such as safe browsing habits, password management techniques, and more. This is essential for keeping employees aware of the most current threats and how they can protect the organization.”

Demi Yilmaz, Co-Founder, Colonist.Io

16) Revamp your Phishing training with the NIST Phish Scale

Phishing attacks are getting more complex and more challenging to detect. They now use sophisticated elements of social engineering to win the trust and bypass human detection. Thus, one-off generic phishing training would not cut it. Security teams need to run phishing simulations that are increasingly challenging on aspects like: 

• Premise alignment with their job roles
• The complexity of detection cues
• Psychological tactics like FOMO, urgency, or threat

With these simulations, security teams can discern the point of failure in the human factor and tailor phishing training to understand better and evade such tactics that threat actors increasingly use. 

17) Penetration testing

To add further depth to their programs, security teams need to be proactive about finding vulnerabilities in their processes and technology and patching them. Penetration testing can help organizations simulate real-world attacks and gauge their resilience against such threats with precision. Findings from penetration tests will also reveal the glaring security gaps that threat actors can exploit to gain unauthorized access to your systems and compromise the integrity or confidentiality of data. 

Moreover, as 2025 is the year when regulations will become even more challenging, penetration tests can reveal gaps in compliance and save organizations their audits and the cost of penalties.

18) Implement measures to contain the breach

Despite the implementation of the cybersecurity best practices for 2025, companies face the possibility of experiencing a breach. Thus, it’s important to focus on preemption and implement measures to contain the impact of a breach. 

These actions include:

• Encrypting data so it’s useless for threat actors even if they get access to it. 
• Maintaining regular backups so integrity and availability of data are never threatened.
• Server hardening to protect access points, ports, and admin permissions.
• Network segmentation to prevent the breach from spreading to adjacent networks and peripherals. 
• Proactive incident reporting to avoid heavy vulnerabilities and fines from regulatory bodies. 

19) Update legacy systems 

As reliable as legacy systems seem to be, they can still be vulnerable to new threats and active exploits in the wild. Many legacy systems continue to have zero-day vulnerabilities that can critically compromise business operations when exploited. However, installing the updated version of the software provided by the vendor patches most of the discovered vulnerabilities and can even help to contain the impact of a zero-day exploit. So, audit your systems and update any dated software or technology. 

20. Use server hardening for cloud infrastructure

Server hardening includes securing servers by reducing their accessible perimeters and, thus, in turn, reducing the vulnerable attack surface. This includes removing unnecessary configurations, network peripherals, and software services running on the servers. However, the biggest piece of the puzzle is to implement the principle of least privilege to secure unauthorized access or abuse of admin privileges, which attackers typically exploit to take over full control of the server. To further solidify defenses, server hardening can be further bolstered by firewalls and intrusion detection systems to stop any threats in their tracks. 

In practice, this method also ensures compliance with regulations like NIST and ISO 27001 and will prevent legal repercussions from non-compliance with these regulatory standards. As cyber threats grow more complex, the role of server hardening in maintaining robust server security becomes increasingly indispensable, making it a cornerstone of practical cybersecurity principles in 2025.
