Ransomware Attacks Surged 126% in 2025. Are You Actually Prepared?

According to a recent report there were 4,701 confirmed ransomware incidents between January and September of this year, alone. 4701 organizations woke to find all their data encrypted, many of them paying the ransom. That’s a 34% increase over the same period last year. Ransomware attacks rose by 126% in Q1 2025 compared to Q1 2024, signaling the most aggressive surge in recent years.

The numbers give you the headline of increased attacks. But the preparedness gap paints the full picture of what this really meant for organizations in 2025.

The Confidence Illusion

69% of businesses believed they were well-prepared before attackers hit them.

Only 22% recovered within 24 hours.

The gap between confidence and capability is where organizations get stuck. We see this often: high confidence in SaaS security posture, low readiness for actual recovery operations.

Here’s what makes this dangerous. 40% of organizations dealt with a SaaS ransomware incident in the past two years. About 40% of those organizations couldn’t fully restore data from backups after the attack—only 46% of ransom-paying victims got their data fully restored, and just 4% recovered all data intact.

Preparation isn’t the same as recovery capability.

Downtime Is the Real Cost

The average ransom demand matters less than you think.

Organizations face 24 to 27 days of disruption. Recovery costs average $5 to $6 million per incident. A single hour of downtime costs approximately $300,000 for most enterprises. For 44% of midsize and large companies, that number exceeds $1 million per hour.

The ransom is often fifty times smaller than the cost of being offline.

Most organizations take about 21 days to recover from a ransomware attack. The full breach lifecycle from initial compromise to containment averages 241 days. Attackers are moving faster. The median time from intrusion to ransomware execution dropped to 5 days in 2025.

Speed defines survival.

SaaS Environments Under Pressure

Cyber threats targeting SaaS surged in 2024. Microsoft 365 and Google Workspace hold a goldmine of sensitive data, communications, and credentials, making them prime targets in the modern threat landscape. Microsoft blocked 7,000 password attacks per second in Entra ID alone. That’s a 75% increase from the prior year.

Phishing attempts jumped 58%, causing $3.5 billion in losses.

92% of organizations use between two and five cloud and SaaS platforms. Attackers exploit weak points in identity and access management to move laterally and escalate attacks. The attack surface expanded faster than most security teams could map it.

Ransomware evolved to target cloud storage and SaaS platforms specifically. Cloud data is just as vulnerable to ransomware attacks as local data. Conventional anti-virus tools don’t cover these environments effectively. 96% of incidents now involve double extortion, where attackers steal data before encrypting it and threaten to leak information publicly if the ransom isn’t paid.

Small and Mid-Market Organizations Face Higher Risk

82% of ransomware attacks in 2021 targeted companies with fewer than 1,000 employees. In Q1 2025, the median size of a victimized organization was just 228 employees.

43% of all cyber attacks hit small businesses. Only 14% of SMBs are prepared to face an attack, yet 88% of all ransomware incidents involve these organizations.

Nearly one in five SMBs that suffered a cyberattack filed for bankruptcy or had to close. 75% of SMBs could not continue operating if hit with ransomware.

The assumption that attackers only target large enterprises is outdated. Small and mid-market organizations often have fewer security resources, making them attractive targets. The impact is disproportionately severe.

What Preparedness Actually Requires

Only 38% of attacked organizations addressed the specific security issue that allowed attackers to enter their systems.

This reveals the core problem. Organizations focus on detection and prevention but underinvest in recovery infrastructure. Automated backup runs continuously. Multiple backup frequencies predict different recovery scenarios. Granular control over what gets backed up and when matters during restoration.

Recovery time measured in hours, not weeks, changes the equation entirely.

We’ve seen organizations reduce ransomware downtime from months to under 2 hours. The difference isn’t luck. It’s architecture. Automated recovery processes, tested restoration procedures, and 24×7 monitoring create the foundation for fast recovery.

Preparedness means you can restore operations before the business impact becomes catastrophic.

The Preparedness Checklist

Ask yourself these questions:

Can you restore from backup in under 24 hours? Most organizations discover their backup strategy has gaps only after an attack. Test your restoration process quarterly.

Do you have visibility into all SaaS applications and browser extensions? Shadow IT creates blind spots. We maintain a registry of 400,000+ assessed browser extensions and apps because attackers exploit the tools you don’t know about.

Have you consolidated your security stack? Managing separate tools for backup, posture management, data loss prevention, and ransomware protection creates coordination delays during incidents. Consolidation reduces response time.

Do you monitor continuously? Attackers move from intrusion to encryption in 5 days. Detection needs to happen in hours, not weeks.

Can you recover granularly? Sometimes you need to restore a single user’s mailbox, not the entire environment. Flexibility in backup selection speeds recovery.

What We’re Building Toward

The SaaS security market is evolving toward unified platforms that handle backup, posture management, and ransomware protection together. Organizations are collapsing their security stacks because fragmentation creates risk.

We’re not just protecting against ransomware. We’re building recovery infrastructure that makes downtime obsolete.

The average cost of a data breach for a U.S. company has surged to an all-time high of $10.22 million in 2025. The question isn’t whether you’ll face a ransomware attack. The question is how long you’ll be offline when it happens.

Preparedness is measured in recovery time.
