14 Cybersecurity Best Practices to Protect Your Organization in 2026

A single data breach now costs the average business $4.44 million, according to IBM's 2025 Cost of a Data Breach Report.

We’re seeing massive losses due to everything from ransomware payments to minor breaches.

If you are running distributed engineering teams, handling customer financial data, or building on cloud infrastructure, you need to seriously assess if your current practices are strong enough to hold up.

Implementing strong cybersecurity best practices protects your business from financial loss, reputational damage, and regulatory consequences.

Let’s take a look at some of the essential cybersecurity best practices every business needs in 2026, with specific steps your team can act on immediately.

Our developers have spent many years in industries where a lack of security results in major regulatory backlash and fines, such as fintech.

These experts have seen, first-hand, what happens when something goes wrong and know what the best steps are.

What Is Cybersecurity?

Cybersecurity usually refers to any measures and protocols that protect the digital well-being of a machine.

In practice, this can look like employing a number of applications, programs, systems, networks, and more to decrease vulnerabilities and respond to cyber threats.

Unauthorized access is one of, if not the greatest, risks to secure networks and devices, especially as users become more aware of the potential consequences of their data being misused, and as global regulations become more stringent.

Why Strong Cybersecurity Matters for Businesses in 2026

Cybercrime costs are projected to reach $15.63 trillion annually by 2029, making it incredibly profitable.

Poor cybersecurity puts personal data at risk, but the stakes are just as high for businesses and government departments that face cyber threats.

Much of the world's information is held digitally, and leaving this data vulnerable puts nearly everybody in danger.

Businesses suffer a great deal from cyber threats. Besides the obvious loss of data, consumers can lose their trust in a business after a data breach occurs, damaging a company's reputation.

The regulatory dimension compounds the financial one.

GDPR fines, CCPA enforcement actions, PCI DSS penalties, and sector-specific regulations mean that a breach often triggers both remediation costs and regulatory consequences simultaneously.

No one is safe either, with one of the biggest fines thus far being a 2023penalty imposed on Meta, at €1.2 billion.

Common Cybersecurity Threats in 2026

While foundational attack types remain, AI has amplified their scale and sophistication, changing the landscape dramatically in recent years.

In general, there are three main types of cybersecurity threats:

1. Cybercrime: occurs when an individual or group targets a system for the purpose of disruption or financial gain
2. Cyber-attack: involves the gathering of information that is politically motivated
3. Cyberterrorism: when the undermining of information systems has the intent to spread fear

As you can see, threats are largely categorized by their objective. But within these three main categories, there are several technical descriptors for how a cyber threat operates that can be used to separate them further.

Malware

Malware is the umbrella term for any malicious software. Cybercriminals and hackers typically create malware with the intention of damaging another user's computer.

Even within this specific category, there are various subsets of malware, including:

• Viruses: a self-replicating program that infects clean code with its replicants, modifying other programs.
• Trojans: malicious code disguised as legitimate software.
• Spyware: software that aims to collect information from a person or organization for malicious purposes.
• Ransomware: software designed to blackmail users by encrypting important files. Ransomware-as-a-Service (RaaS) means attackers don’t even have to code.
• Adware: software that automatically displays unwanted advertisements on a user's interface.
• Botnets: a network of connected computers that can send spam, steal data, or compromise confidential information, among other things.

SQL Injection

SQL injection is an attack consisting of an injection of malicious code into a structured query language (SQL) statement.

It is one of the most common web hacking attacks we come across, and it can damage your database.

Phishing / Social Engineering

Social engineering is the act of manipulating users into giving away private information.

Phishing is a subset of this where an attacker entices a user to reveal sensitive information by first sending a fraudulent message, usually through email.

AI-powered tools can now generate convincing, personalized messages at scale.

It has even gone as far as including voice clones of executives, deployed in real-time calls.

Man-in-the-Middle Attack

Man-in-the-middle (MITM) attacks occur when a perpetrator shimmies themselves between the user and the web application when a new connection is made.

The man in the middle essentially interrupts a data transfer by inserting themselves into the middle of the process, pretending to be a participant and intercepting information.

Advanced Persistent Threats

Advanced persistent threats (APTs) describe intruders or a group of intruders who can remain undetected for an extended period of time.

APTs infiltrate systems, leaving them intact, but steal sensitive data in the process. This poses a particular threat to government and state organizations.

Denial-of-Service Attack

In a denial-of-service attack, cybercriminals interrupt the fulfillment of user requests by overwhelming networks and servers with traffic.

This method usually needs multiple, coordinated systems to work together, so it can sometimes be called a distributed denial-of-service (DDoS) attack.

Supply Chain Attacks

We have recently started seeing a lot more supply chain attacks than in the past.

Rather than attacking a target directly, the attackers compromise a trusted software vendor or service provider whose product the target uses.

Your vendor's breach becomes your breach, even if you have done everything correctly on your side to secure user information.

Usually, we see this come through a trusted, signed software update rather than a suspicious email attachment.

Key Elements of a Strong Cybersecurity Program

Just like how threats are incredibly diverse, cybersecurity has many branches. It can extend from business infrastructures to mobile computing.

Here are most of the layers you will need to think about for a comprehensive security plan:

• Application security: involves processes that help protect applications both in and out of the cloud; security is built in during the design stage
• Information security: securing data from unauthorized access and the protocols involved in doing so, such as the General Data Protection Regulation (GDPR)
• Critical infrastructure security: practices that protect computer systems, networks, and similar assets
• Cloud security: encrypting cloud data to support customer privacy and compliance standards, along with business interests
• Network security: a security measure for protecting computer networks, both wired and wireless
• Disaster recovery & business continuity: tools and procedures, mainly in the form of documentation, are put in place to respond to unforeseen events like natural disasters, power outages, and similar circumstances.
• Operational security: includes the logistical management of security protocols; related to decision-making
• End-user education: aims to educate users about common security threats in order to avoid them
• Zero Trust architecture: a security model where every user, device, and connection must authenticate regardless of network location.

Modern Cybersecurity Challenges to Watch Out For

Cybercriminals have access to more sophisticated tools than ever. We have already mentioned that AI is changing the landscape rapidly. Here are some of the modern cybersecurity challenges businesses face in 2026.

AI-Powered Attacks

As mentioned already, attackers now use AI to craft convincing spear-phishing campaigns, generate deepfake audio of executives requesting wire transfers, and automate vulnerability scanning across millions of potential targets simultaneously.

The irony here is that businesses need AI-assisted detection to match AI-powered offence.

Ransomware-as-a-Service

Criminal groups now operate like software businesses.

There are opportunities to maintain subscription platforms that allow non-technical attackers to deploy ransomware for a share of the proceeds.

The best way we have found around this is reliable, tested, offline backups.

Cyberattacks via Compromised IoT Devices

The Internet of Things (IoT) categorizes a genre of devices that are connected digitally over a network.

A smart fridge or FitBit is a good example of where you can find IoT in everyday life. Of course, this brand of tech comes with particular vulnerabilities.

When networks are insecure, hackers can easily target IoT devices and access and control them remotely. Smart hubs like Google Home and Alexa are among the most hackable devices.

Cloud Security Risks with Data and Applications

Cloud technology is another booming industry with much to offer. Whether it's off-premise servers or a popular cloud app like Slack, cloud computing plays a big part in daily business operations.

Unfortunately, there are a few worrisome risks, including cloud misconfiguration, insecure APIs, and the exposure of sensitive data.

Cloud misconfiguration describes an occurrence where a company has not configured cloud systems correctly. In a figurative sense, this leaves the door wide open for potential hackers.

Given the prevalence of cloud technology, this is not at all uncommon when software as a service (SaaS) providers make regular updates to their applications.

APIs represent one of the fastest-growing attack surfaces.

Insecure API configurations expose sensitive data and allow unauthorised access to backend systems.

Unpatched Vulnerabilities

Attackers can now use automated tools to scan for known unpatched vulnerabilities across millions of targets simultaneously.

Patch management, where you focus on keeping operating systems, libraries, and third-party software current, remains one of the highest-ROI security investments a business can make.

Insider Threats and Compromised Credentials

Insider threats account for a significant proportion of data breaches.

Compromised credentials are one of the top attack vectors.

Limiting access to the minimum required for each role, monitoring for unusual access patterns, and enforcing strong authentication on all sensitive systems reduces exposure from both internal and external threats.

Cybersecurity Best Practices for Businesses

Now that you understand the key threats, let’s take a deeper look at the cybersecurity best practices that produce the largest reduction in breach risk across organisations of all sizes.

You can't totally eliminate the possibility of a cyberattack, but you can do your best to reduce the likelihood of it happening.

1. Enforce Multi-Factor Authentication Across All Systems

Multi-factor authentication (MFA) blocks over 99% of automated account compromise attacks according to Microsoft's internal data.

Every system that holds sensitive data, including email, code repositories, cloud infrastructure, payment systems, and VPNs.

These systems should require MFA as a non-negotiable baseline.

Hardware security keys (FIDO2/WebAuthn) provide the strongest protection. Authenticator apps provide strong protection, while SMS codes are the weakest form.

2. Raise Awareness Through Structured Cybersecurity Training

Phishing and social engineering cause the majority of successful breaches.

Human error is still one of the most reliably exploitable attack surfaces regardless of technical controls.

The solution here is to educate both onsite and offsite employees about cybersecurity best practices and procedures.

Effective cybersecurity training includes things like regular security meetings where you inform your employees about new cybersecurity technologies and developments.

You could also simulate phishing campaigns (not just passive training), provide specific guidance on recognising AI-generated deepfakes and voice fraud, and clear reporting procedures for suspicious activity.

3. Implement Zero Trust Architecture

Never trust, always verify. No user, device, or network connection gets automatic trust, even if they are inside your perimeter.

For businesses with cloud infrastructure and remote teams, Zero Trust replaces the outdated approach of assuming everything inside the firewall is safe.

Practically, you should start with enforcing MFA on all access, applying least-privilege access controls (users get the minimum access their role requires), verifying device security posture before granting access, and logging all access for monitoring and audit.

4. Monitor Company-Issued Devices and Enforce Endpoint Security

While privacy and trust are important things to consider here, monitoring company-issued devices can help prevent cybersecurity issues. Remember these tips for digital internet-ready devices:

• Keep them up to date with anti-virus software
• Deploy endpoint detection and response (EDR) tools
• Analyze the potential point of exposure to security threats
• Find out whether or not employees are honoring the security protocols imposed by the company
• Maintain a device inventory

5. Establish and Maintain Company Security Protocols

Having a centralized strategy for dealing with security issues will ensure that everyone is following protocol and not exposing sensitive information to cyber risks.

A cybersecurity policy of this sort may include:

• Acceptable use policies for company devices and networks
• Suggestions on how to respond if you suspect a cyber threat
• Password management requirements (length, complexity, and a prohibition on password reuse)
• A documented incident response plan with clear roles and contact lists

There should also be clear documentation for how to handle cybersecurity threats when they arise, so workers can follow along whenever they are in need.

6. Use Cloud Applications with Security Configuration Reviews

Opting to use cloud service providers is one way to maintain a high level of cybersecurity, as they use data encryption technology to transfer confidential information.

However, cloud misconfiguration is also one of the most common causes of data exposure.

To make sure you stay safe, build a periodic review process for cloud configurations where you consider access controls, storage bucket permissions, API security settings, and logging configurations.

7. Utilise VPNs and Secure Network Access

A virtual private network (VPN) is one of the best ways to sustain work-from-home cybersecurity.

No matter where they are located, a VPN helps to increase the security of a web session, transferred data, financial transactions, and personal information.

With a VPN, your employees can create a private connection to your business network from a public internet connection. This way, they'll be enabled with online privacy and anonymity.

For businesses with larger teams or more sensitive infrastructure, you may want to consider Software-Defined Perimeter (SDP) solutions.

These are similar, but they provide stronger access control than traditional VPNs, granting access to specific resources rather than the full network.

8. Patch Software and Systems Consistently

An effective patch management process covers everything from operating systems to third-party libraries and dependencies, firmware on network devices and IoT equipment, and even cloud infrastructure configurations.

Automated patching tools are a great option to remove the human bottleneck from routine updates.

You’ll also want to keep an eye out for critical patches, especially those listed in CISA's Known Exploited Vulnerabilities (KEV) catalogue. These should be applied within 24–48 hours of release.

9. Use Multi-Factor Authentication and Strong Password Management

Login credentials are sometimes not good enough to prevent cyber attacks.

Multi-factor authentication asks users to provide more than one form of authentication to prove who they are.

There are a few different ways to do this. Some apps use security questions in addition to login credentials, but these are frequently guessable or publicly researchable.

TOTP (time-based one-time passwords) can be useful for mitigating such risks. These passwords only work once, and they are active for only a short period of time.

Another method is biological authentication. This is when the app uses physical data, such as fingerprint or facial recognition.

Password managers eliminate the human tendency to reuse passwords across systems.

10. Limit Access with Least-Privilege Controls

You should limit how much access employees have to sensitive business information. By giving more people access, you open more avenues for security breaches.

Only give employees access to the apps and data they absolutely need. You can always give someone more privileges if and when the need arises. This is a much safer model than giving everyone open access.

Conduct access reviews quarterly. When an employee changes roles or leaves, revoke access immediately.

Also, make sure that any privileged accounts with administrative access to critical systems use separate credentials and are monitored more closely than standard user accounts.

11. Turn On Firewalls and Network Segmentation

Firewalls are a basic line of defence on a computer system. But something as simple as turning off firewalls while working can leave you and your employees vulnerable.

Make it a required policy that all developers have firewalls on at all times for their work devices.

Network segmentation limits the blast radius of a breach. If an attacker compromises one part of your network, segmentation prevents them from moving laterally to more sensitive systems.

Payment systems, customer data storage, and development environments should each sit in isolated network segments with explicit access controls between them.

12. Encrypt Everything

There are a couple of ways to go about encrypting your information.

The first is through employee devices. By requesting that your employees encrypt their devices, if an employee's device is lost or stolen, no one will be able to access their data.

Secondly, you should encrypt the backups of any software and hardware you have that is connected to your business. Whether your business is managing an app, website, or hard drive, these things do fail or otherwise get infected by malware.

Follow the 3-2-1 backup rule, where you have three copies of data, on two different media types, with one stored off-site or offline.

13. Build and Test an Incident Response Plan

An incident response plan defines in advance what happens when something goes wrong.

Tabletop exercises can help you test this plan and reveal gaps in the plan before an attacker does.

Containment and eradication focus on stopping the bleeding by isolating compromised systems, blocking attacker communication channels, resetting compromised credentials, and removing malware.

14. Consider Cyber Insurance

Cyber insurance has become a meaningful component of a business's risk management strategy.

Policies cover breach notification costs, regulatory fines, legal fees, forensic investigation, and business interruption losses. A lot of insurers now mandate MFA, patch management, and backup policies as conditions of coverage.

Make sure that you review coverage annually as your business and the threat landscape both evolve.

What To Do If a Breach Happens

When you're working with distributed teams, sometimes a breach happens anyway, and when it does, you'll need a response plan.

Here are a few of the scenarios where you should plan for breaches:

• A developer loses a device
• An unauthorized party accesses your infrastructure
• A team member is 'let go' under unfriendly circumstances
• A phishing attack compromises a staff member's credentials
• A third-party vendor suffers a breach that exposes data you shared with them

It's your responsibility to respond to them appropriately.

Sometimes this means being ready to disable user accounts, take a server offline, or shut down production entirely.

In essence, you'll want to do whatever is necessary to contain the breach and make certain further information isn't put in jeopardy.

Regulatory notification timelines are also very strict, with GDPR requiring breach notification within 72 hours.

The key is to have a developer on hand who is familiar with not only general cybersecurity but also your specific industry and its requirements.
