Tips for Preventing Breaches in 2025

In 2024, the world experienced some of the biggest data breaches in history, affecting major industry players such as AT&T, Snowflake (and consequently Ticketmaster), and more. The cost of these data breaches for US businesses amounted to over $9 million on average, highlighting the significant financial and reputational damage caused by such incidents.

Despite the severe consequences of data breaches, a staggering 98% of companies continue to engage with vendors who have experienced breaches. While there has been an increased emphasis on vetting vendors for security measures, businesses rely on these external partners to deliver essential goods, services, and technology to support their operations. This reliance on vendors underscores the importance of implementing robust security measures to protect sensitive data and information assets.

One key strategy for businesses to safeguard their data in 2025 is through proactive security reviews of vendors. By conducting regular security assessments, companies can identify and mitigate potential risks before they escalate into costly breaches. These reviews involve evaluating various aspects of a vendor’s security practices, including data encryption, compliance with regulations such as GDPR and HIPAA, and incident response protocols.

Continuous monitoring and real-time audits play a crucial role in tracking a vendor’s security posture and identifying emerging vulnerabilities. By implementing quarterly security assessments for vendors handling critical infrastructure, businesses can stay ahead of evolving risks and ensure comprehensive security oversight. Leveraging automation tools and AI-driven security solutions can streamline the assessment process, improve accuracy, and enhance threat detection capabilities.

In light of recent breaches like the SolarWinds incident, which could have been mitigated with better continuous monitoring, businesses must prioritize security reviews as a proactive defense against cyber threats. While no security measure is foolproof, consistent security reviews empower companies to select vendors that align with their security standards, ultimately reducing the risk of cyberattacks, breaches, and regulatory fines.

Another crucial aspect of securing data in 2025 involves updating legacy systems to address vulnerabilities associated with outdated software and hardware. Businesses should assess these legacy systems for weaknesses and invest in upgrades or replacements where necessary. Segregating legacy systems from shared networks and implementing segmentation tactics can contain security threats and protect the overall network.

Advanced security measures like encryption and access controls are essential components of a comprehensive security strategy to protect sensitive data. Encryption protocols, both for data at rest and in transit, should be implemented using robust algorithms like AES-256 and protocols such as TLS to prevent unauthorized access and interception of information.

Stringent access controls, including multifactor authentication and role-based access control, help restrict access to sensitive data to authorized personnel only. Regularly reviewing and updating these access permissions based on changing roles and responsibilities within the organization strengthens overall security posture and minimizes the risk of unauthorized access.

By identifying and addressing IT infrastructure vulnerabilities, conducting thorough risk assessments, and implementing advanced security measures, organizations can enhance their security posture and ensure compliance with regulatory requirements. As the threat landscape continues to evolve, businesses must remain vigilant and adaptable, continuously refining their security protocols to stay one step ahead of cyber threats in 2025 and beyond.
