Ranking the Top Best Printers for Cybersecurity

Network Printers – the Initial Attack Vector

Connected devices to company networks and the internet are "baked into" our daily routines. Digital security, physical security, financial security, business identities, and individual identities meld together into a collective vulnerability.¹ Cyberattacks using automated artificial intelligence systems further exacerbate the problem.² Networked printers are a significant exploitable pathway for cyberhackers to access otherwise secure networks.³ Modern printers are the initial attack vector for many hackers attempting to breach an organization's network because they are traditionally a weak link. Since cybercriminals target networks that are the easiest to exploit, according to the FBI,⁴ it makes sense to purchase network printers that offer the best security protection from unauthorized users.

Why Do Cybercriminals Select Printers When Hacking Networks?

From the viewpoint of cybercriminals, business printers are the gateway to an organization’s network. Printers tend to receive the least amount of attention when it comes to network security, making them low hanging fruit for cyberattacks. Cybercriminals will seek the path of least resistance to gain entry to company networks. Office printers with little protection and known vulnerabilities are ripe for hacking.

Disadvantages of Vulnerable Printer Security

Printer network security focuses on preventing cyber threats and issues affecting businesses with unsecured copiers. A printer cybersecurity event can produce the following results for an organization:

• Financial Loss
• Loss of customer database
• Transaction records loss
• Employee data loss
• Identity theft
• Regulatory noncompliance
• Loss of company trade secrets to competitors
• Loss of productivity
• Customer lawsuits
• Unauthorized use of equipment and network resources
• Some thriving companies failed and are no longer in business as a result of a cyberbreach

How to Select the Best Cybersecure Printer

With an array of printer brands available in the market, discerning the most cybersecure models can be challenging. We meticulously evaluated and ranked the top printers from leading brands to simplify this decision-making process based on their cyberattack vulnerability. Unlike many product rankings on the internet with baseless rank orders and links to affiliate websites for monetarization, this printer ranking uses data collected from government-sanctioned websites. These unaffiliated websites list cybersecurity vulnerabilities and exposures (CVE) of IoT devices to cybercriminals. This information comes from organizations that are not benefiting from manufacturers. These organizations do not benefit by skewing figures to favor a particular manufacturer. Instead, the sources are government-sponsored and endorsed to help organizations improve printer network security. Examining brands of printers with measurable data for their past and current vulnerabilities is a better measurement of security than rankings without any analytical data.

Printer Cybersecurity

Not all office printers are alike. Some manufacturers extensively research networked printers' vulnerabilities and develop safeguards to help prevent a cyberbreach. Manufacturers focusing on developing printers for businesses, enterprises, and respected organizations, rather than concentrating on price-conscious consumers, tend to manufacture the best printers to combat cybersecurity. Companies like Brother, Kyocera, Ricoh, Sharp, and Xerox invest heavily in securing their print devices. The tabular data below provides evidence of print manufacturer efforts toward network security.

Our Method of Ranking

To determine which network printers offer the best cybersecurity functions out-of-the-box, we will use the registrar from the National Vulnerability Database and CVE details to evaluate the security track record for the top brands of office printers. CVE is a registered trademark of the MITRE Corporation. The U.S. Department of Homeland Security (DHS) sponsors the CVE and the Common Weakness Enumeration (CWE) programs.⁵ The CVE Program seeks "to identify, define, and catalog publicly disclosed cyber security vulnerabilities."⁶

Our evaluation and ranking will initially use three measurements. These measurements use objective data and subjective classification. Together, they help ascertain the best secure printers for office networks.

3 Tests for Printer Security Vulnerabilities

1. Common Vulnerabilities and Exposure (CVE)
2. The Common Vulnerability Scoring System (CVSS)
3. The Exploit Prediction Scoring System (EPSS)

#1  CVE: Measuring Vulnerability and Exposure

The CVE measurement evaluates the history of common cybersecurity vulnerabilities and exposure (CVE). We examined each brand's exploitable history over the past 11 years from CVE reports of the vulnerability of their office devices. This objective measurement is the total number or sum of all identified vulnerabilities for the brand. We then drill down to examine the vulnerabilities logged only during 2023 from January 1 through November 14. The tally for 2023 tells us something about a manufacturer's attention to detail in removing all of the previous years of CVEs and protecting against foreseeable security vulnerabilities. Accurately forecasting security issues and protecting against them is the hardest part of cybersafety to prevent unauthorized access. We tallied the number of vulnerabilities by brand, adding them to a comparison chart for a side-by-side analysis.⁷

#2  CVSS: Measuring Severity of Vulnerability

Not all vulnerabilities are equal. Some are critical, while others offer limited or low exposure. Each vulnerability receives a numeric score for its severity level between 0 and 10. 10 represents the highest severity level, while 0 represents zero severity. The severity level assignment is somewhat subjective, but it is vital to prioritize which vulnerabilities need to be dealt with expeditiously. In ranking the top printers for the best security, the CVSS score is a significant factor. There are four levels of severity—Low, Medium, High, and Critical. A "Critical" rated printer is more prone to unauthorized access and a costly cybersecurity breach. Below is a chart depicting the severity levels derived from their CVSS score.

#3  EPSS: Measuring the Probability of Exploitation

EPSS provides efficient, data-driven vulnerability management. This open, data-centric initiative utilizes current threat information from CVE and real-world exploit data. The EPSS model generates a probability score based upon a percentage between 0 and 1 (or 0% and 100%), where a higher score or percentage signifies an increased likelihood of a vulnerability to exploitation.⁸

Leveraging EPSS for Enhanced Vulnerability Management

EPSS evaluates the probability of exploitation activity, constituting just one facet in a risk-based approach to vulnerability management. Consequently, EPSS is not a standalone risk score. Factors like the accessibility of vulnerable assets to attackers, the nature of the vulnerability's weakness, and the asset's purpose and value, among others, warrant consideration when prioritizing which vulnerabilities necessitate attention.

EPSS exclusively relates to the threat component. Organization managers must factor in numerous aspects of the network vulnerability, their network access, and the network devices before deciding whether to remediate or postpone remediation. Nonetheless, a lower EPSS score should signify a reduced threat score (EPSS never reaches zero), thus potentially lowering the overall risk when other variables remain constant. Risk analysis is undeniably intricate. EPSS provides an additional assessment within the comprehensive landscape of organizational networks to help make the best purchase decisions.
