If you are in a hurry -> Suggestions to Avoid Such Claims in the Future

Introduction

In April 2025, Stanley Steemer, a leading U.S. carpet cleaning and restoration company, agreed to settle a class action lawsuit for $700,000.

The lawsuit stemmed from a data breach that exposed sensitive customer information due to inadequate cybersecurity measures. The breach allegedly compromised both personal and financial data of Stanley Steemer's customers, triggering legal action for negligence, violation of consumer protection laws, and failure to provide timely notification of the breach.

This settlement brings forth critical lessons for cybersecurity executives on the importance of securing customer data and maintaining transparency during a breach.

This analysis covers the key elements of the Stanley Steemer lawsuit, the claims made, technical lapses, and practical steps CISOs can implement to avoid such legal issues.

Background: The Company and the Breach

Stanley Steemer is a well-known provider of residential and commercial cleaning services, particularly focusing on carpet and upholstery cleaning, air duct cleaning, and tile and grout cleaning.

The company serves millions of customers across the United States. As a result, it collects substantial amounts of personal data, including names, addresses, phone numbers, and payment information.

In early 2025, Stanley Steemer experienced a significant data breach. The breach reportedly exposed customer names, addresses, phone numbers, and payment details stored in its databases.

This breach occurred due to what was described as “inadequate security protocols”, including weak network defenses, insufficient data encryption, and a lack of regular security audits.

The breach was detected by a third-party security firm in February 2025, and it was revealed that hackers had gained access to Stanley Steemer's systems and extracted sensitive customer information over a period of several weeks .

Legal Fallout: The Class Action Lawsuit

Following the breach, customers who were impacted filed a class action lawsuit against Stanley Steemer, accusing the company of failing to implement adequate cybersecurity measures to protect their data.

The lawsuit alleged that Stanley Steemer’s failure to detect the breach in a timely manner and its delayed notification to customers exacerbated the damage caused by the breach.

The class action was filed in the U.S. District Court for the Southern District of Ohio.

• Plaintiffs and Prosecutors: The plaintiffs in the class action lawsuit were individuals whose personal data was compromised during the breach. The prosecuting attorneys were a coalition of law firms, led by ClassAction.org, which specializes in data breach cases .

• Settlement: In April 2025, Stanley Steemer reached a $700,000 settlement with the plaintiffs, which included compensation for affected customers and measures to enhance the company's cybersecurity practices . The settlement also required Stanley Steemer to provide credit monitoring services to all affected individuals for one year .

  
  

Claim Types: Legal Categories

The claims in this lawsuit primarily involved the following legal categories:

1. Negligence: The core of the lawsuit was based on the allegation that Stanley Steemer was negligent in protecting customer data. Plaintiffs argued that Stanley Steemer failed to implement adequate security measures to prevent unauthorized access to personal information .

2. Breach of Contract: Another key claim was that Stanley Steemer violated its Terms of Service and privacy policies, which implied a commitment to protect the data customers provided. Plaintiffs argued that the company did not fulfill its contractual obligations to safeguard sensitive information .

3. Consumer Protection Violations: The lawsuit also cited violations of consumer protection laws, specifically in relation to the failure to disclose the breach in a timely manner and the lack of transparency regarding the nature and scope of the attack .

4. Unjust Enrichment: The plaintiffs claimed that Stanley Steemer was unjustly enriched by failing to invest in necessary cybersecurity measures, leading to the breach and its consequences .

5. Privacy Violations: Given the sensitive nature of the data involved (names, addresses, phone numbers, and payment information), the plaintiffs also invoked privacy violations under applicable federal and state laws, asserting that Stanley Steemer’s failure to protect data resulted in a violation of their personal privacy rights .

   
   

Specific Claims Made in the Lawsuit

The plaintiffs outlined specific allegations in their complaint:

• Failure to Implement Adequate Security Measures: The plaintiffs claimed that Stanley Steemer did not have sufficient technical and organizational measures in place to protect sensitive data from unauthorized access. This included the lack of encryption for stored data, weak network defenses, and failure to patch known vulnerabilities .

• Delayed Breach Detection: The lawsuit argued that the breach was not detected in a timely manner, allowing hackers to extract customer data for weeks before it was identified .

• Inadequate Incident Response and Notification: One of the most significant claims was Stanley Steemer’s failure to notify affected customers promptly. The breach wasn’t disclosed until several months after it had been discovered, leaving customers unaware of the potential risks to their financial and personal information .

• Failure to Provide Adequate Protection for Personal Data: The lawsuit highlighted that sensitive data, including credit card details, was stored in an unprotected format and was easily accessible to cybercriminals .

• Lack of Regular Security Audits and Updates: Another critical claim was that Stanley Steemer failed to conduct regular security assessments, leaving its systems vulnerable to attack .

  
  

Technical Claims: Cybersecurity Failures

From a technical perspective, the lawsuit centered around several key cybersecurity failures:

1. Weak Data Encryption: The most significant technical failure was Stanley Steemer’s failure to properly encrypt sensitive customer data both at rest and in transit. As a result, even if hackers gained access to the system, they could extract data in an unprotected format .

2. Inadequate Network Defenses: Stanley Steemer’s network defenses were reportedly insufficient to prevent a breach. The lawsuit pointed to the company’s use of outdated security protocols, which hackers were able to bypass using known exploits .

3. Failure to Detect the Breach: The breach went unnoticed for several weeks, which the plaintiffs argued was a direct result of poor network monitoring and lack of a proactive threat detection system. Stanley Steemer failed to identify unusual activity on its network that could have been indicative of an attack .

4. Inadequate Incident Response Plan: Once the breach was identified, Stanley Steemer reportedly lacked a well-defined incident response plan, causing delays in mitigation and notification. The company failed to quickly lock down compromised accounts or inform affected users .

5. Lack of Multi-Factor Authentication (MFA): The breach may have been mitigated had Stanley Steemer implemented multi-factor authentication (MFA) to protect customer accounts. Without MFA, an attacker could gain access to accounts with only a stolen password .

   
   

Suggestions to Avoid Such Claims in the Future

The Stanley Steemer case serves as a stark reminder of the importance of robust cybersecurity practices.

To prevent similar claims, CISOs can consider the following recommendations:

1. Implement Strong Data Encryption

Ensure that all sensitive data is encrypted both in transit and at rest. This adds a layer of security that can prevent attackers from accessing usable data, even if they manage to breach the system. Encryption should follow industry standards such as AES-256 for data at rest and TLS 1.2 or higher for data in transit.

2. Adopt Multi-Factor Authentication (MFA)

Implementing MFA significantly reduces the risk of unauthorized access to accounts, particularly when passwords are compromised. MFA should be mandatory for all employees, contractors, and users accessing sensitive information.

3. Conduct Regular Security Audits and Penetration Testing

Regular security audits and penetration testing should be part of an ongoing cybersecurity strategy. This helps identify vulnerabilities before they are exploited by attackers. Regular vulnerability scanning should be conducted to ensure that systems are up-to-date and secure.

4. Establish a Strong Incident Response Plan

Every organization must have a well-defined incident response plan. This plan should detail how to quickly identify, contain, and mitigate breaches. Additionally, it should include clear procedures for notifying affected individuals promptly, as delays in notification can worsen reputational damage and lead to legal liabilities.

5. Strengthen Network Monitoring and Detection Capabilities

Invest in advanced network monitoring tools to detect suspicious activities in real-time. Implement Security Information and Event Management (SIEM) systems that can help aggregate and analyze logs from various systems to identify potential security incidents early.

6. Ensure Compliance with Data Protection Laws

Stay informed about the evolving data protection laws and regulations, such as the General Data Protection Regulation (GDPR) and California Consumer Privacy Act (CCPA). These laws often have strict requirements for data protection and timely breach notifications, which can serve as guidelines for your own organization’s data handling practices.

7. Enhance Employee Training and Awareness

Employees should be regularly trained on cybersecurity best practices, including recognizing phishing attempts, using strong passwords, and reporting suspicious activities. Security awareness programs can help prevent many breaches caused by human error.

8. Proactive Communication

In the event of a breach, always prioritize transparency and timely communication with affected users. Swift and honest communication can mitigate legal claims and reduce the potential for consumer backlash. Additionally, providing affected customers with credit monitoring and other forms of assistance can demonstrate a commitment to protecting their interests.
