How to build a resilient data security strategy 

Data is the lifeblood of business. So, it’s constantly at high-risk of being lost or stolen. From ransomware attacks to insider threats, you face mounting pressure to protect sensitive information. This blog explores four pillars of data security - encryption, data loss prevention, identity access management, and data erasure - and how they work together to safeguard your digital assets. 

 Encryption: Locking down your data 

Encryption transforms readable data into coded formats, making it inaccessible without the correct key. It’s a frontline defence against unauthorised access - whether data is at rest (laptops, smartphones or tablets) or in transit (web, VPNs or email attachments).  

Use encryption to secure online transactions like e-commerce payments and banking, protect personal data on devices and in cloud storage, and safeguard digital communications through secure messaging and VPNs. Encryption’s also critical for industries like healthcare and government to protect sensitive information. 

According to IBM’s 2024 Cost of a Data Breach Report, breaches involving encrypted data cost $220,000 less on average than those without encryption.  

Encryption is also required for regulations like HIPAA for the healthcare industry and PCI DSS standards for financial institutions.  

Data Loss Prevention (DLP): Keeping your sensitive data in-house 

DLP tools monitor and control data movement to prevent leaks - whether accidental or malicious. They’re essential for compliance and protecting intellectual property.  

A 2025 Gartner report found that 90% of organisations using DLP saw a 60% reduction in accidental data exposure.  

Identity Access Management (IAM): Who gets in and why 

IAM ensures that only your authorised users can access specific systems and data. It’s about verifying identity and managing your permissions effectively. 

Microsoft reports that 99.9% of account compromise attacks can be prevented with multi-factor authentication (MFA). 

Secure databases

Protect your data - whether you're a business or developer, with secure databases that are encrypted and enforce role and user-based access control. Comply with regulations like GDPR which recommend the use of encryption. Build customer trust as they can be reassured their data is kept secure. Plus you get peace of mind your data and database backups are secure against cyber threats and data loss.

Data Erasure: When deletion isn’t enough 

Deleting files doesn’t mean they’re gone. Secure data erasure ensures that information is permanently removed and unrecoverable - critical for compliance with regulations like GDPR. 

Blancco’s 2025 State of Data Santisation report found that around a quarter of certain devices were refurbished for resale or donation without certified erasure - a major compliance and security gap that needs to be fixed. However, the report also found that 96% of organisations now have or are creating data sanitisation policies. This shows organisations are starting to become more aware of the importance of data security, especially when it comes to data erasure. 

Build your resilient data security strategy 

Data security isn’t a one-time fix - it’s an ongoing commitment. By investing in encryption, DLP, IAM, and secure erasure, you can protect your reputation, maintain trust with your clients, and stay ahead of evolving threats. These tools also help you achieve compliance with many security frameworks.
