2025 SMB Threat Report: Key Takeaways For Regulated Industries

SMBs In The Crosshairs As 2025 Comes To A Close

As 2025 draws to a close, one thing is clear. For small and medium businesses, this was not just another noisy year in cybersecurity. It became a turning point.

The data from the past two years tells a consistent story. In 2024, 94% of small and medium businesses reported at least one cyberattack. In the first half of 2025, weekly incident volume nearly doubled again. Many leaders admitted that a single major incident could put them out of business. The numbers support that fear. Around 6 in 10 small and medium businesses that suffer a serious attack close within 6 months.

The average breach costs for this segment now range from $120,000 to $140,000 per incident. That figure does not include long-term brand damage, lost customer trust, or regulatory actions.

At the same time, the fundamentals are still not where they need to be. Only about 14% of small and medium businesses report that their defenses are adequate for advanced threats. Fewer than 40% have a formal vulnerability management program. The attack surface continues to expand while many organizations attempt to defend it with tools, habits, and staffing models that belong to an earlier era.

For regulated industries, the gap is even more dangerous. Healthcare, financial services, manufacturing, and defense contractors are navigating strict privacy and security expectations, tighter cyber insurance scrutiny, and an increasingly active regulatory environment. Falling behind has a direct cost in fines, penalties, lost contracts, and reputational harm.

What 2025 Taught Us About Ransomware And AI Phishing

Looking back at 2025, two threat themes stand out for small and medium businesses in regulated industries. Ransomware and AI-driven social engineering.

Ransomware remained the single most disruptive threat. The 2025 breach data shows that 88% of small and medium business breaches involved ransomware, compared with 39% for larger enterprises. Across all organizations, roughly 44% of breaches involved ransomware this year. More than 80% of ransomware attacks targeted companies with fewer than 1,000 employees.

Median ransom payments landed around $115,000, with some averages above $550,000. Once you factor in forensics, legal support, recovery, lost revenue, and reputational harm, the real financial impact commonly ranges from $120,000 to the 7-figure territory. Around 75% of small and medium businesses say they could not continue operating after a major ransomware event.

Timing patterns in 2025 made this even more troubling. Just over 50% of ransomware attacks occurred on holidays or weekends. Many organizations reduced security staffing by 50% or more during those periods. The majority of ransomware payloads were deployed outside regular business hours.

Phishing also changed shape. In 2025, most phishing messages were machine-generated. Studies show that more than 80% of phishing emails are now AI-generated, with click rates several times higher than older attempts.

Business email compromise increasingly used synthetic content, voice cloning, and deepfake audio or video. Employees trained to look for red flags suddenly faced messages that looked correct in every way.

Regulated Industries Learned Hard Lessons In 2025

The 2025 numbers confirm that the threat landscape is not evenly distributed.

In healthcare, breach costs remained the highest of any industry. Average incident costs ranged from $7.4 million to $9.77 million. In Q3 2025 alone, more than 139 breaches compromised 9.5 million patient records. Healthcare providers accounted for nearly 74% of affected organizations and 90% of impacted individuals. Most incidents were hacking or IT-related, and the compromised data was not encrypted.

Financial services saw continued pressure. Around 65% of financial institutions were hit by ransomware in 2024, and that trend continued. Nearly 50% experienced successful data encryption. Common entry points included compromised credentials, exploited vulnerabilities, and malicious email.

Manufacturing remained a top target for supply chain and operational disruption. For the third consecutive year, it ranked as the most targeted sector. More than 22% of attributed attacks targeted manufacturers. Threat actor activity increased by more than 71% between 2024 and early 2025.

In each of these industries, incidents extended beyond the initial victim. Healthcare organizations answered to regulators and patients. Financial firms faced auditors and investors. Manufacturers struggled to meet obligations to large buyers and government partners.

Third-Parties, Vulnerabilities, And Credentials In 2025

Third-party involvement in breaches doubled year over year, rising from 15% to 30%. Nearly 90% of organizations expressed concern about supply chain risk, and more than 70% experienced a significant third-party incident in recent years.

Only 26% of organizations had integrated incident response planning into third-party risk management.

Vulnerability exploitation also grew. About 20% of breaches began with exploitation. In 2024, more than 29,000 new vulnerabilities were published, including 4,600 rated critical. More than 50% were easy to exploit. Many organizations took 32 days or more to apply patches. Only 38% of small and medium businesses had a formal vulnerability management program.

Credential abuse remained a major factor. Around 22% of breaches began with stolen or misused credentials. 88% of basic web application attacks involved stolen credentials. Nearly 46% of endpoints infected with information stealers were unmanaged or Bring Your Own Device (BYOD) systems.

From Threat Statistics To Cyber Resilience In 2026

The 2025 data makes one point clear. Prevention is no longer enough. The priority for 2026 must be cyber resilience.

Multi-factor authentication remains one of the most effective controls. Nearly 100% of compromised accounts lacked multi-factor protection. Adoption among small and medium-sized businesses remains significantly lower than among large enterprises.

Zero Trust approaches continued to accelerate. In 2025, more than 81% of organizations reported at least partial implementation, and the market is projected to grow significantly through 2030.

Incident response maturity also proved essential. Organizations with documented and regularly tested plans saw shorter breach lifecycles and significantly lower costs. Without a plan, containment times stretched by months, and costs increased by millions.

Security awareness training continued to deliver meaningful results. Between 60% and 74% of breaches still involved the human element, yet organizations with structured programs reported fewer employee-driven incidents and strong returns on training investments.

How Regulated SMBs Can Use 2025 To Shape 2026

As 2026 approaches, regulated small and medium businesses face a crucial choice. They can treat the 2025 threat report as another alarming dataset or use it as a guide for what to address next.

Cyber insurers now expect multi-factor authentication, documented incident response plans, encrypted backups, endpoint detection and response, vulnerability management, and ongoing training.

Security budgets are expected to increase in 2026, but a budget alone will not solve the problem. Leaders must direct spending toward the controls that truly reduce risk.

Before 2026 arrives, make sure your organization is resilient – not just reactive. Check out our strategic readiness tool, Building a Resilient Cyber Posture for 2026, and see how your risk posture aligns with today’s realities. Get your copy and start your 2026 readiness plan.

From Reclamere’s perspective, the lesson of 2025 is straightforward. You cannot control when an attacker will come. You can control how prepared you are. Organizations that strengthen identity controls, close vulnerability and third-party gaps, invest in people, and mature their incident response programs will enter 2026 from a position of resilience.
