Why Third-Party Security Matters More Than Ever in 2025

In today's connected business world we observe a concerning trend emerging. According to Verizon's latest security research, breaches involving third-party suppliers and vendors have doubled in just one year. These incidents now account for 30% of all data breaches – a huge increase that affects businesses of all sizes. Today, GDC Services takes a look at the latest analytics and highlights the importance of securing your work with service providers and how to do that properly.

The Connected Business Challenge

Think about how many external partners your business works with – software providers, consultants, service contractors, cloud platforms, and more. Each of these relationships, while essential for business operations, creates a potential security risk.

The latest research shows that attackers have figured out an effective strategy: why try to breach a well-protected company directly when you can target their smaller, potentially less-secure vendors instead. This approach has become very common.

According to the 2025 Verizon Data Breach Investigations Report, breaches involving third parties have doubled in just one year, now accounting for 30% of all security incidents.

The same report revealed that ransomware attacks have increased by 37% compared to last year, with ransomware now present in 44% of all analyzed breaches.
In high-profile breaches analyzed by security researchers, 54% of ransomware victims had their domains appear in leaked credential logs prior to being attacked – showing how third-party credential theft often precedes major breaches. Once attackers have compromised a trusted partner, they can often gain access to their larger clients' systems and data through existing connections and credentials.

As security expert noted during the Verizon DBIR launch event, "Criminals are smart and pragmatic... they count every cent," preferring to enter through less-protected partners rather than attacking fortified enterprises directly.

Modern Security Technology That Works

While these findings are concerning, they also highlight the importance of choosing third party partners with robust security practices. GDC Services’s approach combines advanced technology with internationally recognized security standards to protect both our systems and yours.

We've invested in cutting-edge security systems that work together to identify and stop threats before they cause damage, such as:

• 24/7 Security Monitoring: Our SIEM/XDR platform continuously watches all activity across our networks, systems, and applications, spotting suspicious behavior instantly.

• Quick Response Systems: When potential threats are detected, our systems can automatically take protective actions within seconds – not hours or days.

• Complete Visibilty: Unlike basic security tools, our solution sees and monitors everything in our environment, leaving no blind spots where attackers could hide.

• Up-to-Date Protection: Our systems are constantly updated with the latest information about new threats and attack methods.

Internationally Certified Security Practices

Technology alone isn't enough. This is why we've earned ISO 27001 certification – the gold standard for information security. This certification, which few companies achieve, confirms that we:

• Systematically identify and address security risks,
• Follow documented security policies and procedures,
• Protecting physical and digital assets,
• Carefully control who can access information,
• Regularly test and evaluate our security,
• Continuously improve our security program.

It's verification from independent experts that our security program meets rigorous international standards. The ISO 27001 standard has seen steady global growth of approximately 20% annually, with major enterprises like Microsoft, Google, Apple, and Amazon maintaining this certification because they recognize its value in protecting both their operations and their customers.

What This Means for Your Business

When you choose us as your partner, you benefit from:

• Verified Security: Independent auditors have confirmed our security controls meet international standards, so you don't have to take our word for it
• Around-the-Clock Protection: Our advanced security systems provide continuous protection, rather than the periodic security checks typical of many providers.
• Faster Threat Identification: Our systems can quickly spot potential security issues, minimizing potential damage by preventing attackers from gaining a foothold.
• Comprehensive Safeguards: Our security program addresses risks across all aspects of our operations – technology, people, and processes. We continually monitor our systems, provide transparent updates about our security posture, and take preventive actions before the threats can affect our services.

Making the Secure Choice

The dramatic increase in third-party breaches highlighted in the latest research makes choosing the right partners more important than ever.

By selecting providers with both ISO 27001 certification and advanced security technology, you significantly reduce your exposure to the growing third-party risks affecting so many companies today.
