What is data loss prevention?
Data breaches are becoming more costly and harder to manage. In 2024, the global average cost of a data breach hit a record $4.88 million, up 10% from the year before. According to Statista, the healthcare sector took the biggest hit, with an average cost of $9.77 million per breach, while the financial sector followed at $6.08 million.
To combat these rising costs and risks, businesses need robust data protection measures in place. Data Loss Prevention (DLP) is about protecting digital information from loss, theft, or unauthorized access. It ensures data stays private, accurate, and available while helping businesses comply with security regulations like HIPAA for healthcare data or PCI DSS for payment card information.
Key measures include encryption, which secures data so only authorized users can access it, and access controls, which restrict who can view or modify sensitive information. Backup and recovery solutions help restore lost data, while data masking hides confidential details. By implementing these practices, organizations can prevent breaches, protect customer trust, and comply with industry regulations.
Common causes of data loss
Data loss occurs when important information is deleted or corrupted. Some causes are more common than others, and each requires specific prevention measures. Understanding these threats helps businesses protect their data.
Human error
Mistakes happen, and human error is one of the main reasons data is lost. For example, accidentally deleting files, entering the wrong information, or mishandling sensitive data can lead to serious problems. In fact, IBM’s Cost of a Data Breach Report 2024 found that human error is behind up to 95% of cybersecurity breaches.
While checking entries twice and limiting access to important files can help, these methods depend on manual actions and still leave room for error. To lower the risk of data loss, businesses should use automated security policies and tools that centralize data protection.
Data Loss Prevention (DLP) strategies, whether through enterprise browsers or other solutions, enforce security policies across all users, reducing errors and ensuring consistent protection. Regular training and clear data-handling procedures further support a strong culture of security.
Insider threats
Insider threats come from employees or trusted individuals with access to sensitive data. Sometimes, mistakes, like sending an email to the wrong person, cause data security incidents. Other times, disgruntled employees may intentionally steal or expose information. The IBM report also states that insider threats account for 34% of data leaks.
Strict access controls and user activity monitoring can help. Government agencies, like the U.S. Department of Defense, use advanced monitoring to prevent insider threats. While most businesses don’t need military-level security, they should still take insider risks seriously.
Cyber-attacks
Cybercriminals use malware, ransomware, and phishing attacks to steal or damage data. IBM X-Force data shows that malware deployment was the most common attack method in 2024, making up 43% of incidents. Ransomware accounted for 20%, while backdoors and crypto miners were found in 6% and 5% of cases, respectively.
Strong cybersecurity measures—such as firewalls, antivirus software, and employee training, are crucial for protection. But in web-based SaaS environments, enterprise browsers add an extra layer of defense. They help protect against threats like malware, ransomware, and phishing by using centrally managed security policies, access controls, and other built-in functionalities. This works alongside traditional security measures to keep your systems safe.
Hardware failures
Storage devices can fail, causing data loss. A server crash, hard drive failure, or power surge can make critical data inaccessible. While less common, hardware failures can be devastating.
Regular backups and redundant storage solutions help prevent permanent data loss. Think of it as having a spare tire ready in case of a flat.
Natural disasters
Floods, earthquakes, and fires can destroy physical storage devices. For example, Hurricane Sandy in 2012 caused widespread data loss for businesses.
While natural disasters can’t be prevented, businesses can prepare. Off-site backups and cloud storage solutions keep data safe and accessible, even if disaster strikes.
Why Data Loss Prevention matters to your business
As businesses rely more on digital tools, data flows across various devices, cloud services, and networks, creating a “borderless” environment. This is further complicated by:
- Hybrid work models
- Bring Your Own Device (BYOD) policies
- Increased use of contractors
- The rapid growth of web-based SaaS apps
These factors introduce new risks, making it harder to track and protect sensitive data. Without strong security measures, your data could be exposed, stolen, or misused.
Data Loss Prevention (DLP) helps businesses secure their most valuable information, including customer data, financial records, and intellectual property. DLP also ensures compliance with regulations and helps prevent costly data breaches caused by accidental leaks or cyber threats.
As this environment grows more complex, traditional security measures are often no longer enough. A tailored approach, especially within web-based SaaS environments, is critical to safeguarding your data effectively.
Do you know where your sensitive data is?
In modern work environments, traditional DLP methods are no longer enough, especially as more people use their own devices (BYOD) and rely on web-based SaaS apps.
Why is DLP critical? Because it helps businesses gain full visibility into how data flows across their network. It allows IT and security teams to monitor and enforce policies, preventing unauthorized sharing of sensitive information like customer records and financial details.
Enterprise browsers provide a more granular solution. They track data flow within the browser in real time. This allows IT and security teams to block the unauthorized sharing of sensitive information, whether employees are using corporate or personal devices.
With granular access and centralized security policy control, businesses can create stronger, more flexible security rules to protect their most valuable assets.
Employees can also put data at risk, not only external threats
Most companies focus on external cyber threats but overlook insider risks, employees, or partners who unintentionally or intentionally expose sensitive data. According to Verizon’s Data Breach Investigations Report, 28% of breaches involve insiders.
Traditional Data Loss Prevention (DLP) tools have primarily focused on preventing accidental data leaks. They do this by blocking sensitive files from being shared through unsecured channels like USB drives or personal email accounts. These tools also detect unusual activity and restrict access to prevent data theft. If a security incident occurs, traditional DLP can quarantine or encrypt the data to protect against exposure.
Enterprise browsers take DLP a step further by offering a more granular, real-time approach. This is especially useful in today’s web-focused environments. With centrally managed security policies, enterprise browsers can implement DLP controls directly within the browser, addressing data risks at the source.
This includes features like:
- Copy/paste restrictions to prevent unauthorized data transfer
- Download limitations to control sensitive file movement
- Real-time monitoring to spot and block risky behavior instantly
By using these advanced controls, businesses can protect data more effectively and prevent accidental or intentional leaks.
The cost of a data breach is higher than you think
A single data breach can lead to financial penalties, reputational damage, lost customers, and legal consequences. According to IBM’s Cost of a Data Breach Report 2024, on average, it takes 191 days to detect a breach, giving hackers plenty of time to steal valuable information.
DLP minimizes this risk by enforcing strict security policies, reducing the chances of a costly data breach. Organizations that protect their data avoid regulatory fines, lawsuits, and the financial impact of lost business.
Stay compliant and avoid costly fines
Regulations like GDPR, HIPAA, and PCI DSS require businesses to implement strict data protection measures. Non-compliance can lead to fines of up to 4% of global annual revenue or restrictions on business operations.
DLP helps businesses meet compliance requirements with built-in policy templates and reporting tools. It simplifies audits and ensures sensitive data is protected according to industry standards.
Secure data across all devices, including BYOD and IoT
With employees using personal devices, data moves beyond traditional networks. Add IoT into the mix, and the security challenges grow even more complex. That’s why businesses need to adopt BYOD security practices, such as DLP.
DLP, according to security policy, monitors and protects sensitive data across all devices, whether it’s being accessed, stored, or transmitted. By working alongside other security measures, DLP helps businesses prevent unauthorized data sharing and reduce security risks in an increasingly mobile world.
Take control of your data before it’s too late
Data protection isn’t just about avoiding breaches. It’s about maintaining trust, staying compliant, and keeping your business secure. Implementing a strong DLP strategy gives your organization the tools to prevent data loss, control sensitive information, and stay ahead of advanced threats.
Top 7 best practices for data loss prevention
Implementing a Data Loss Prevention solution combines cybersecurity best practices with advanced technology to protect sensitive information. DLP solutions typically focus on four key areas:
- Prevention: Monitors data in real-time and blocks unauthorized access or suspicious activity
- Detection: Identifies unusual behavior and improves data visibility to catch potential threats early
- Response: Tracks and reports data access and movement to streamline incident response
- Analysis: Helps security teams understand high-risk activity and improve future protection strategies
DLP gives businesses real-time visibility and control, helping safeguard data, reduce risks, and stay compliant. To learn more, download our free PDF on best practices for data loss prevention.
Step 1: Conduct a data inventory & risk assessment
Start by identifying and classifying all sensitive data within your organization. Determine where the data is stored, how it moves, and who can access it. Conduct a thorough risk assessment to understand potential vulnerabilities and threats.
Use data discovery software to automate this process. By gaining insight into your data’s landscape, you can tailor your DLP efforts.
Step 2: Use encryption to protect your files
Encryption turns data into a code that only authorized users can read. It helps protect sensitive information from cybercriminals. When data needs to be accessed, a decryption key is used to turn it back into its original form.
Encryption safeguards data both when it’s stored and when it’s being transferred. Encryption is required by data protection laws like GDPR and PCI DSS, as it helps reduce the risk of data loss and helps businesses stay compliant with regulations.
NordLayer’s advanced encryption protocols, such as AES 256-bit and ChaCha20 encryption, further strengthen your data’s confidentiality and integrity.
Step 3: Enable access controls
Access controls limit who can see your sensitive data. This can include defining data classification, access controls, encryption standards, and incident response procedures. You can strengthen access with the following solutions:
- Network Access Control (NAC) ensures that unauthorized users and devices are kept out of your business network.
- Identity and Access Management (IAM) verifies that every user accessing the network is properly authorized.
- Network segmentation restricts access so employees and contractors only see the data they need to do their jobs, nothing more.
- Cloud Firewall lets you control who and how to access internal resources and cloud tools, adding an extra layer of protection.
Step 4: Monitor data access
Monitoring allows you to track who accesses data and helps quickly spot unauthorized activity. By tracking user interactions and reviewing logs, businesses can detect breaches and respond faster. Real-time monitoring solutions can alert security teams about suspicious behavior.
Additionally, Device Posture Security monitors access to every application on every device. Real-time alerts inform security teams about suspicious behavior, while automated monitoring tools help identify anomalies and uncover potential breaches. Regular audits should measure incident detection and response times, data breach reductions, and cost savings.
Step 5: Conduct regular security audits
Regular security audits help identify vulnerabilities in systems that could lead to data loss. These audits examine software, hardware, networks, and policies. Once vulnerabilities are found, businesses can take steps to fix them, such as updating software or improving security protocols.
Evaluate your DLP using these key performance indicators (KPIs):
- Incident detection & response times: How quickly data breaches are detected and resolved
- Reduction in data breaches: A decrease in the frequency and severity of data breaches
- Cost savings: Financial benefits from preventing breaches and avoiding regulatory penalties
Regular monitoring and audits, combined with the integration of NordLayer’s security solutions, will help optimize your DLP strategy. This approach ensures ongoing data protection and supports your SOC 2 compliance efforts.
Step 6: Train your team
Employee training is key to preventing data breaches caused by human error. As we have already mentioned, 95% of breaches happen because of mistakes made by people. That’s why teaching staff to spot phishing emails, use strong passwords, and follow data protection rules can reduce these risks.
Regular training keeps employees aware of current threats and reinforces their role in protecting sensitive information. It also helps build a strong security culture.
Step 7: Create a strong incident response plan
Data breaches can still happen, so it’s crucial to have a plan for responding quickly. The plan should include identifying the breach, containing it, notifying affected individuals, investigating the cause, and taking corrective actions to prevent future breaches.
A clear incident response plan minimizes damage and helps businesses recover quickly. In short, having an incident response plan is crucial for managing data breaches and minimizing their impact.
