Organizations faced an average of 1,876 cyberattacks per quarter in 2024, a 75% increase year over year. The pressure on businesses and their IT teams keeps growing. And small businesses are not exempt. Over 60% rank cyber threats among their top concerns, and nearly 67% of small businesses that experienced a cyber attack reported financial difficulties within six months.
Cyber threats are constant and they are getting worse. This guide covers the most common threats businesses face today and the concrete steps you should take to protect your data, systems, and operations.
Common Cyberthreats Faced by Businesses
Businesses have always been targets for cybercriminals. The integration of artificial intelligence into attack methods has made those attacks faster, more targeted, and harder to detect. Understanding what you are up against is the first step toward building a defense that holds.
Ransomware
Ransomware encrypts your files and locks you out of your own systems. Attackers demand payment to restore access. The average ransomware attack costs businesses over $1.85 million when you account for downtime, recovery, and lost revenue, according to Sophos research. Even businesses that recover their data without paying face weeks of disruption. Ransomware groups target organizations of all sizes because smaller businesses tend to have weaker defenses and fewer resources to respond.
Phishing Attacks
Phishing is one of the most common entry points attackers use. Criminals send fraudulent emails or messages designed to trick your employees into handing over passwords, credentials, or financial details. One successful phishing email gives an attacker access to your entire network.
Generative AI has made this threat significantly worse. Criminals now produce convincing phishing emails, deepfake audio, and synthetic video at scale. The quality of fake messages has improved to the point where trained employees still get fooled. IBM reports that phishing is involved in over 40% of all data breaches.
Bad Bots
Bad bots are automated programs built to attack websites, mobile apps, and APIs. A common tactic is credential stuffing, where bots use stolen username-and-password pairs to break into accounts automatically. Because people reuse passwords across services, one leaked credential list gives attackers access to thousands of accounts.
Criminals also use bots to launch Denial-of-Service (DoS) attacks, flooding your network or website with traffic until it goes down. For any business that depends on its online presence, even a few hours of downtime causes real financial and reputational damage.
Insider Threats
Threats do not always come from outside. Employees and contractors cause harm too, both intentionally and by accident. An employee who clicks a malicious link, misconfigures a server, or improperly shares data creates the same damage as an external attacker. The Ponemon Institute estimates that insider-related incidents cost businesses an average of $15.4 million per year. These threats are difficult to detect because the activity looks like normal business behavior.
Supply Chain Attacks
Criminals compromise a trusted vendor or software provider to gain indirect access to their actual targets. Your own security posture does not matter if one of your suppliers is the weak point. The 2020 SolarWinds attack demonstrated the scale of this risk: a single compromised software update affected over 18,000 organizations, including multiple US government agencies. A single compromised vendor has the potential to affect hundreds of downstream businesses simultaneously.
Best Practices to Protect Sensitive Data and Information
You do not need an unlimited budget to defend your business. You need consistency, layered defenses, and a workforce that knows what to look for. The following practices address the most common vulnerabilities attackers exploit.
Enforce Multi-Factor Authentication
Enforce multi-factor authentication (MFA) for every user account and company application. A stolen password alone will not give an attacker access. Options include fingerprint or facial recognition, authenticator apps, and hardware security keys. Microsoft reports that MFA blocks over 99% of automated account attacks. Given how often credentials appear in data breaches, MFA is one of the highest-return controls available to you.
Follow Bot Detection Protocols
Use bot detection tools to stop automated threats before they reach your customers and systems. Reliable bot mitigation tools block credential stuffing, scraping, and denial-of-service attacks. Look for solutions with device fingerprinting, behavioral analysis, real-time detection, and AI integration. Without bot protection in place, your login pages, checkout flows, and APIs are open to automated attacks around the clock.
Regularly Update and Patch Software
Attackers actively scan for systems running unpatched vulnerabilities. The time between a vulnerability being disclosed and it being exploited is often days, not months. The 2017 Equifax breach, which exposed the personal data of 147 million people, traced back to an unpatched software vulnerability. Update and patch all software, applications, and operating systems promptly. Automate the process wherever you are able to eliminate delays.
Limit Access to Sensitive Information
Give employees only the access they need to do their job. This principle, known as least privilege, limits the damage from both compromised accounts and insider threats. Review permissions regularly. Revoke access immediately when employees change roles or leave the organization. A former employee with active credentials is an open door.
Back Up Data Regularly
Regular, tested backups give you an option other than paying a ransom when an attack hits. Store backups in a secure, offsite or cloud-based location isolated from your main network. A backup stored on the same network as your primary systems will likely be encrypted alongside them during a ransomware attack. Test your backups on a scheduled basis. A backup you have never tested is a backup you cannot rely on.
Build an Incident Response Plan
No defense stops every attack. You need a documented plan for what happens when one gets through. Your plan should specify who handles what, how to contain the attack, how to communicate with customers and regulators, and how to restore operations. According to IBM, organizations with a tested incident response plan save an average of $2.66 million per breach compared to those without one. Test and update the plan at least once per year.
Secure Your Network
Your network is the pathway attackers use to move through your systems once they get in. Segment your network so a breach in one area does not automatically give access to everything else. Require employees to use a VPN when working remotely, especially on public Wi-Fi. Use firewalls to filter traffic at the perimeter. Disable unused ports and services. These steps reduce how far an attacker gets even when your other defenses fail.
Train Your Employees
Human error contributes to the vast majority of successful cyberattacks. Run regular security awareness training that covers phishing recognition, password hygiene, safe browsing habits, and how to report suspicious activity. Use simulated phishing exercises to test what employees have learned and identify who needs more support. Make reporting easy and free of blame. Early reports stop attacks that would otherwise go unnoticed for weeks.
Conduct Regular Security Audits
Your defenses need testing, not just setup. Schedule periodic security audits to identify gaps in your controls, outdated configurations, and access permissions that have accumulated over time. Penetration testing, where a security professional attempts to breach your systems the way an attacker would, gives you a realistic view of your exposure. Treat audit findings as a prioritized action list, not a report to file away.
Consider Cyber Insurance
Cyber insurance does not prevent attacks, but it reduces the financial impact when one succeeds. A good policy covers costs related to data recovery, legal fees, regulatory fines, customer notification, and business interruption. Review policies carefully. Many exclude coverage for attacks linked to unpatched vulnerabilities or inadequate security controls, so the practices described in this guide are prerequisites for getting the most out of coverage.
Invest in the Right Security Tools
Endpoint antivirus is a starting point, not a complete solution. Firewalls, email filtering, network monitoring, and threat detection systems add the layers you need. Many modern tools use machine learning to identify behavior that traditional detection would miss. Match your toolset to your actual risk profile and budget, then build from there as your needs grow.
Cyberattacks will happen. The businesses that recover are the ones that prepare before an attack occurs, not after. Enforce MFA, deploy bot mitigation, keep software patched, restrict access, back up your data, secure your network, train your team, audit your defenses, and document your response plan. Do those things consistently and you give your business a real defense against the threats most likely to cause serious damage.
