Best Cyber Security Checklist for Small Business

Cyberattacks of all forms increased significantly in 2025. Attackers took advantage of the pandemic’s disruption, distant worker networks, and widespread fear of COVID.

70% of firms that store data in the cloud had encountered a security problem in the previous 12 months, while spear-phishing attempts increased by 667 percent in March 2020.

According to the Sophos 2021 Threat Report, which examined the most common assaults last year and their reasons, organizations failing to implement cybersecurity best practices was a role in a number of security events.

According to the paper, “a failure to pay attention to one or more components of fundamental security hygiene has been identified as the core cause of many of the most severe assaults we’ve reviewed.”

Often, small companies are unsure of the steps necessary to secure their operations. Basic IT security is comprised of many levels that operate in concert to prevent data, endpoints, and networks from being hacked. If one of those levels is absent, there is a weakness in the security system.

Cyberattacks that are successful cost organizations of all sizes an average of $200,000 per victim.

Pro Tech Guy has compiled an important Small Organization Cyber Security Checklist that you can use to verify that you have all of the necessary elements in place to safeguard your business.

Checklist of Critical Cybersecurity Measures for Small Businesses

Private Virtual Network (VPN)

When workers are linked to insecure networks, the development of mobile working and the significant increase in remote work creates a significant security concern.

Since the epidemic started, around 20% of businesses have encountered a security breach caused by a work-from-home employee.

A company VPN is critical for maintaining data security regardless of where workers work. A virtual private network encrypts internet connections, ensuring them security regardless of whether they are connected to a public Wi-Fi network.

Endpoint Security

Endpoints are devices that connect to and store corporate data through a network. Endpoint protection is required for those devices (desktops, laptops, and mobile devices, among others) to safeguard their security against hackers.

This includes any employee-owned devices used for work-related purposes. It’s quite straightforward for ransomware or malware to propagate from an infected endpoint to a cloud storage provider that syncs data. Thus, a single compromised device might result in a widespread breach of your network.

The fundamental endpoint protection measures that you should implement include the following:

  • Antivirus/Anti-malware
  • Management of patches and updates
  • The device’s screen is locked.
  • A method for remotely locking or wiping a misplaced or stolen device

Filtering of DNS

Malicious phishing websites have developed into a significant menace. Once an unwary person accesses one of these sites through a phishing email link, it may infect their device with malware or create a bogus login page in order to steal their credentials.

88 percent of phishing emails now include links to dangerous websites rather than file attachments. This is because anti-malware software often fails to detect linkages.

DNS filtering (a.k.a. web filtering) safeguards consumers from accessing harmful phishing websites. It examines each URL that a user attempts to access and, if a problem is discovered, redirects the user to a warning page. This may help avoid network infection even if a user clicks on a malicious link.

Backups

Ransomware was identified as a significant kind of malware in the Sophos 2021 Threat Report. Ransomware assaults have grown in popularity and are now being used as a money-making plan by huge underground criminal groups.

When consumers have a cloud backup of all their data, recovering from a ransomware attack is far simpler and less expensive. Businesses may avoid paying a ransom and avoid wasting time determining what to do.

Backups help safeguard businesses from data loss occurrences caused by natural catastrophes, hard drive breakdowns, and other causes.

Protection Against Email Spam/Phishing

Phishing emails are the primary vector via which all forms of cyberattacks are launched. Phishing is a very effective method for attackers to get access to a user’s computer and deceive them into installing malware or providing their password or credit card information with a bogus website.

Phishing attacks are becoming more sophisticated, including techniques such as impersonating the domain of a reputable organization as the sender. These emails often deceive users, even those who have received awareness training.

A critical precaution against phishing emails reaching user inboxes is an email/spam phishing filter. This program may identify questionable emails and store them on your mail server in a quarantine folder rather than distributing them to users.

This drastically reduces your company’s vulnerability to phishing attacks.
