The need for open source audits in cybersecurity M&As

In today’s world cybersecurity is about more than just antivirus software and endpoint security software. Technical due diligence is a given in almost every acquisition or investment involving technology companies. While a tech diligence checklist can be daunting for acquirers and targets alike, a new study published by (ISC)2 confirms that auditing for cybersecurity is—and should be—at the top of the checklist. 

In fact, the (ISC)2 survey of 250 US-based M&A professionals showed that 100 percent of the executives and M&A advisors surveyed agreed that cybersecurity audits have become standard practice.

To understand why companies are auditing for cybersecurity, we must first understand the risk. In the same study, (ISC)2 found that security breaches that come to light during the due diligence process can derail a transaction; in fact, almost half (49 percent) of participants said they had seen it happen. 

Unsurprisingly, 52 percent of respondents viewed an audit revealing weak security practices as a liability. The same number said a post-acquisition security breach in an acquired company has affected the share value of a publicly traded organization. It’s clear a cybersecurity breach can significantly affect shareholder value. During M&A integration, it’s critical to expose and deal with any potential weakness at a target company.

Measuring risk

Cyberrisk is measured by comparing a company’s operational processes against some form of standard and reporting the results. How that evaluation is accomplished varies, including the standard chosen, the manpower consumed, and the credibility of the resulting report which rests upon the consulting firm’s reputation for its cybersecurity expertise. 

Assessing cybermaturity against a widely recognized standard is the best option for tech due diligence. The Cyber Security Framework (CSF)

‘People use smartphones more but invest less in their security’: New report claims McAfee and Norton remain the most loved antivirus brands as users ditch lesser-known security products for free tools like Microsoft Defender or Apple Xprotect

  • Most smartphone users rely on built-in security without additional protection
  • Paid antivirus adoption on mobile devices continues to decline steadily
  • A significant share of users remains unprotected or unaware of safeguards

Most Americans now use their smartphones more than their computers, but very few spend money to protect those phones from hackers, new research has claimed.

A Cybernews report surveyed over 1,000 American adults, and found only 18% of mobile phone users pay for third-party antivirus software.

Built-in tools like Microsoft Defender and Apple’s XProtect have become the default choice for most people, while McAfee and Norton lead the paid market for the second year in a row.

Smartphone owners are skipping extra security protections

Most consumers believe the security features already built into their phones are sufficient for daily use, and see little reason to spend extra money on something they think they already own for free.

Roughly 14% of mobile users say they have no cybersecurity tools installed at all on their devices. Another 16% cannot even name what protections they currently have in place.

On desktop computers, the situation looks very different, with far fewer unprotected machines and much wider adoption of third-party security tools.

Windows Defender and Apple’s native security features now serve as the primary defense for 53% of computer users and 51% of mobile users.

Most people choose these free options because they trust the operating system vendor to provide adequate baseline protection.

Paid antivirus adoption on computers has actually grown by 2% since last year, reaching 41% of users.

On mobile devices, however, third-party antivirus usage has dropped by roughly 10% over the same period, falling from 28% to just 18%.

Mobile users face growing risks

Ransomware attacks targeting smartphones are still less common than those aimed at computers, but the threat landscape is shifting rapidly.

Users who depend solely on the free security tools that came with their phones may be underestimating what modern cybercriminals can do.

Paid subscriptions have gained ground over free alternatives, yet the majority of mobile owners still avoid spending money on dedicated protection.

Cybercrime exposure does influence some users to change their habits, but personal experience is not the main driver of adoption for most people.

Many users employ layered security approach, combining antivirus with VPNs and password managers.

However, the data shows that a large segment of mobile users remain either unprotected or unsure about what safeguards they have.

Established brands like McAfee and Norton continue to benefit from user trust, while lesser-known products struggle to gain acceptance even when their features are comparable.
