Ransomware Surge in 2025 Demands Isolation and Containment

Ransomware is not slowing down. It is accelerating.

A recent report covered by TechRepublic highlights a troubling reality. Ransomware groups claimed more than 2,000 attacks in just three months, and overall incidents rose 52 percent in 2025 compared to the previous year. According to the article, 6,604 ransomware attacks were recorded globally in 2025, with some months setting new records for activity.

For business owners, these numbers are not just statistics. They represent operational disruption, financial loss, reputational damage, and in some cases, business failure.

Ransomware Is Scaling Faster Than Security

The TechRepublic coverage, based on Cyble’s 2025 threat landscape report, reveals several critical trends:

• Ransomware activity continues to climb year over year.
• Supply chain attacks nearly doubled, allowing attackers to exploit trusted third parties.
• Multiple industry sectors are being targeted, including manufacturing, professional services, construction, and technology.
• The pace of attacks has continued into early 2026 with no meaningful slowdown.

What makes this surge especially concerning is the industrialization of ransomware. Ransomware as a Service models allow less experienced attackers to launch sophisticated campaigns. Automation and AI tools allow threat actors to scale operations rapidly. The barrier to entry is lower, but the impact on victims is higher.

Businesses are facing more attackers, more campaigns, and more sophisticated techniques than ever before.

The Problem With Detect and Respond

Most organizations still rely heavily on a detect and respond strategy. This approach assumes that:

1. You will detect malicious activity quickly.
2. You will respond before meaningful damage occurs.

The problem is that ransomware moves fast. By the time detection tools trigger an alert:

• Files may already be encrypted.
• Sensitive data may already be exfiltrated.
• Attackers may have moved laterally across multiple systems.

Detection is reactive. Response is time consuming. Meanwhile, business operations are interrupted and costs continue to mount.

The 2025 surge in ransomware proves that traditional approaches are not stopping attackers at scale. If detection alone were enough, we would not be seeing thousands of successful incidents in a single quarter.

Isolation and Containment: A Smarter Security Model

Instead of waiting to detect malicious behavior, organizations need to prevent it from causing harm in the first place.

Isolation and containment changes the equation. Rather than trying to identify every possible new strain of ransomware, this model:

• Restricts how applications interact with the operating system.
• Prevents unauthorized processes from modifying protected resources.
• Stops ransomware from encrypting files or spreading across endpoints.

If malicious code cannot interact with critical system assets, it cannot complete its objective.

This approach significantly reduces the blast radius of an attack. Even if malware lands on a device, it is contained and prevented from executing harmful actions.

Why AppGuard Matters Now

AppGuard is built on the principle of isolation and containment. With a proven 10 year track record protecting highly sensitive environments, AppGuard shifts endpoint security from reactive detection to proactive prevention.

AppGuard:

• Blocks malicious processes from interacting with protected system resources.
• Enforces policy based controls that prevent unauthorized behavior.
• Protects against both known and unknown threats without relying solely on signatures or behavioral detection.

In an environment where ransomware groups claimed over 2,000 attacks in just three months, businesses cannot afford to rely only on tools that alert them after compromise begins.

AppGuard helps stop ransomware before encryption, before data theft, and before operational shutdown.

The Business Impact of Doing Nothing

When ransomware hits, the consequences extend beyond IT:

• Revenue loss due to downtime
• Legal and regulatory exposure
• Customer trust erosion
• Long term brand damage

The surge documented in 2025 shows that attackers are not slowing down. They are becoming more organized, more aggressive, and more successful.

Continuing to rely solely on detect and respond strategies leaves your business exposed to these risks.

Time to Shift the Strategy

The cybersecurity landscape has changed. Ransomware groups are executing thousands of attacks annually. Supply chain weaknesses are being exploited. New threat actors are entering the ecosystem constantly.

It is time to move from Detect and Respond to Isolation and Containment.

If you are a business owner or executive concerned about ransomware resilience, we invite you to talk with us at CHIPS. We can show you how AppGuard’s proven isolation and containment approach can prevent the type of incidents described in the TechRepublic report.

Do not wait for detection alerts to tell you your business has been compromised.

Let’s put containment in place before ransomware has a chance to execute.
