Cybersecurity Trends 2026: What to Prepare For

Every year brings a new round of security predictions. Most of them are vague. This one isn’t, because by late 2026 we have hard data on what attackers actually did in 2025 and clear dates for new rules.

Here’s the short version. Attackers are breaking in through unpatched software more than stolen passwords. AI is making fraud more convincing. Ransomware is still everywhere, even as fewer victims pay. Regulators in the US and EU are tightening reporting deadlines. And defenders are moving to passkeys, zero trust and long-term post-quantum planning.

Below are the 9 trends that matter most, grouped into threats, regulation and defenses, with a short action list for each.

Trends at a glance

Threat shifts

Attackers in 2026 are faster and more automated, but they still need a way in. These 4 shifts matter most.

1. Attackers break in through software flaws

Verizon’s 2026 Data Breach Investigations Report found that 31% of breaches now start with the exploitation of software vulnerabilities, making it the top entry point, ahead of stolen credentials. VPNs, firewalls, file transfer tools and other edge devices are frequent targets because they sit on the internet and often go unpatched.

AI is speeding this up. Google’s Threat Intelligence Group reported in May 2026 that state-linked groups were using AI to analyze known vulnerabilities at scale, and that a criminal group used a zero-day exploit Google believes was developed with AI help.

Action list - Keep an up-to-date list of every internet-facing system. - Patch anything in CISA’s Known Exploited Vulnerabilities catalog first, ideally within days. - Retire unsupported systems. If you still have Windows 10 PCs, see our guide on Windows 10 end of support. - Put admin panels and remote access behind a VPN or zero trust access, not open on the internet.

2. AI makes fraud more convincing

The FBI’s Internet Crime Complaint Center (IC3) received more than 22,000 complaints referencing AI in 2025, with adjusted losses of over $893 million. Verizon’s 2026 report says generative AI now bolsters about 15% of the attack techniques it tracks. The biggest practical change is that phishing emails are fluent and voice clones are realistic, so “spot the typo” training no longer works.

Action list - Require callback verification on a known number for any payment or bank detail change. - Set code words for executives and finance staff. - Train staff to judge the request, not the writing quality. - Read our breakdown of how hackers use AI for tactic-by-tactic defenses.

3. Ransomware persists, but fewer victims pay

Ransomware showed up in 48% of breaches in Verizon’s 2026 report, even as ransom payouts shrank and more organizations chose not to pay. Criminals respond by stealing data before encrypting it, so they can threaten to leak it even if you restore from backup.

Action list - Keep offline, encrypted backups and test a restore every quarter. - Turn on MFA for remote access, email and backup consoles. - Write an incident response plan with your bank, insurer and IT contacts. - Follow our step-by-step ransomware protection guide.

4. Fraud losses keep rising

Total losses reported to IC3 passed $20 billion in 2025 across more than 1 million complaints. Investment fraud was the largest category, followed by business email compromise (BEC) at about $3 billion and tech support scams. BEC rarely involves malware; it relies on convincing someone to send money to the wrong account.

Action list - Adopt dual approval for wires and payee changes. - Ask your bank about positive pay and payment alerts. - Know how to report fast: call your bank, then file at ic3.gov. Our guide to business email compromise has the full playbook.

Key takeaway: The 2026 threat picture rewards boring discipline. Fast patching, callback verification and tested backups stop more real-world attacks than any single new tool.

Regulation shifts

Regulators want to hear about incidents sooner and expect stronger baseline controls. Here are the 3 changes to track.

1. Critical infrastructure incident reporting is coming

The Cyber Incident Reporting for Critical Infrastructure Act of 2022 (CIRCIA) will require covered entities to report substantial cyber incidents to CISA within 72 hours and ransom payments within 24 hours. Those deadlines are written into the law, but reporting only becomes mandatory once CISA’s final rule takes effect. CISA published its proposed rule on April 4, 2024, and as of October 2026 says it is still working on the final rule, which has slipped several times.

Action list - Check whether you fall into one of the 16 critical infrastructure sectors and could be a covered entity. - Build a 72-hour incident reporting process now, including who decides an incident is “substantial”. - Watch CISA.gov/CIRCIA for the final rule and effective date.

2. The EU Cyber Resilience Act starts to bite

The EU Cyber Resilience Act (Regulation (EU) 2024/2847) affects any company selling software or connected products in the EU, including US companies. Since September 11, 2026, manufacturers must report actively exploited vulnerabilities and severe incidents: an early warning within 24 hours, a notification within 72 hours and a final report later. Reports go through ENISA’s Single Reporting Platform. The full security requirements for products apply from December 11, 2027.

Action list - If you sell software, apps or connected devices in the EU, confirm whether your products are in scope. - Set up a vulnerability intake and disclosure process with 24-hour escalation. - Start building a software bill of materials (SBOM) for each product.

3. US sector rules are in flux

Several US rules are being written, revised or paused at once, so check the status before you plan around them:

• SEC public company disclosure. The SEC’s 2023 rules require public companies to disclose material cybersecurity incidents on Form 8-K, generally within 4 business days of determining materiality. Industry groups have asked the SEC to rescind or narrow the rule, but as of this writing it remains in effect.
• HIPAA Security Rule. HHS proposed a major update in January 2025, including stronger requirements for encryption, MFA and asset inventories. It has not been finalized, and the existing Security Rule still applies.
• CMMC for defense contractors. Phase 1 of the Cybersecurity Maturity Model Certification program began on November 10, 2025. In July 2026 the Department of Defense suspended the move to Phase 2 and began a program review, while self-assessments and NIST SP 800-171 obligations remain.
• State privacy laws. More state comprehensive privacy laws took effect in 2026, many with data security duties. Our US state data privacy laws guide tracks them.

This is not legal advice. Confirm your obligations with counsel.

Action list - Assign one person to track the rules that apply to your sector. - Map your current controls to the strictest rule you’re likely to face. - If you sell to enterprises, expect security questionnaires and reports like SOC 2.

Defense shifts

Defenders are moving away from passwords and network perimeters, and starting to plan for quantum-era encryption.

1. Passkeys and phishing-resistant MFA go mainstream

CISA describes FIDO/WebAuthn authentication, which includes security keys and passkeys, as the only widely available phishing-resistant MFA. Major platforms now support passkeys broadly, and many businesses are moving admins and finance staff to them first. Text message codes still beat no MFA, but they can be phished or intercepted.

Action list - Enforce MFA on every account, starting with email, banking and admin accounts. - Move high-risk users to passkeys or security keys. See passkeys and the end of passwords. - Adopt a password manager for everything that doesn’t support passkeys yet.

2. Zero trust and identity become the perimeter

With staff, apps and data spread across the cloud, the network edge no longer defines who is trusted. Zero trust replaces “inside the network equals trusted” with continuous checks on identity, device health and access needs. For smaller businesses, this often starts with conditional access in an existing identity provider rather than a big new platform. Our explainer on zero trust security covers the basics.

Action list - Remove standing admin rights and use just-in-time access where possible. - Require managed, updated devices for access to sensitive apps. - Review third-party and vendor access every quarter.

3. Post-quantum cryptography planning begins

NIST published its first post-quantum cryptography standards (FIPS 203, 204 and 205) in August 2024 and says it will deprecate and ultimately remove today’s quantum-vulnerable algorithms, such as RSA and elliptic curve cryptography, from its standards by 2035, with high-risk systems moving earlier. The concern is “harvest now, decrypt later”: attackers stealing encrypted data today to decrypt it once quantum computers are capable. Learn more in our guide to quantum computing for businesses.

Action list - Inventory where you use encryption, especially for long-lived sensitive data. - Ask key vendors about their post-quantum roadmap. - Favor products that support crypto-agility, meaning algorithms can be swapped without a rebuild.

Where to start: your 90-day priority list

If you can only do a few things this quarter, do these in order:

1. Turn on MFA everywhere and move admins and finance staff to passkeys.
2. Patch internet-facing systems against the CISA Known Exploited Vulnerabilities catalog.
3. Write a callback and dual approval rule for payments.
4. Test a full restore from offline backups.
5. Write or update a 1-page incident response plan with a 72-hour reporting step.
6. Confirm which regulations apply to you: CIRCIA, the EU Cyber Resilience Act, SEC, HIPAA, CMMC or state privacy laws.

Conclusion

The cybersecurity trends of 2026 aren’t exotic. Attackers are faster thanks to automation and AI, regulators want to hear about incidents sooner, and the defenses that work are well known. Patch quickly, harden logins, verify money requests and know your reporting deadlines. Do those 4 things well and you’ll be ahead of most organizations, whatever 2027 brings.
