What changed this year	Why it matters
Exploitation overtook stolen credentials as the leading breach entry point. AI, identity, third-party, telemetry and cryptographic risks also intensified.	It’s time to prioritize exposed vulnerabilities, complete identity coverage and AI governance, along with other recommendations below for 2027.

1. Vulnerability Exploitation Is Now the Leading Door In

TRICK: Exploitation is outrunning traditional patch cycles

• Vulnerability exploitation accounted for 31% of initial access in uncovered breaches, overtaking stolen credentials as the leading vector.
• Ransomware appeared in 48% of breaches, illustrating how frequently initial access can escalate into significant business disruption.

TREAT: Prioritize exposed, exploitable and business-critical weaknesses

• Prioritize remediation by exposure level, asset criticality, exploitability and CISA’s Known Exploited Vulnerabilities catalog, not severity score alone.
• Set measurable remediation targets by risk tier and report exceptions, overdue items and accepted risks.
• Ensure continuous scanning of attack surfaces and validate that patches actually closed the weakness.

2. AI is Accelerating Attacks and Exposing Governance Gaps

TRICK: AI is increasing attack speed while governance lags

• AI-driven attacks increased 56% and added an average cost of about $1 million per breach.
• 68% of breached organizations lacked AI governance policies for managing approved and unapproved AI use.
• Organizations using AI and automation extensively for security saved an average of $1.93 million versus organizations using none.

TREAT: Govern AI access, data and accountability before scaling

• Create an inventory of approved AI tools, models, agents, owners, data sources, integrations and business uses.
• Require risk review before deployment, including data classification, prompt and output handling, access rights, human oversight, logging and supplier terms.
• Treat AI agents as non-human identities: use least privilege, short-lived credentials, runtime monitoring and accountable human ownership.
• Use AI defensively for detection, triage and remediation, while independently testing model outputs and maintaining human decision authority.

3. Human Identity Gaps Remain a Primary Ransomware Entry Point

TRICK: Ransomware exploits phishing, stolen credentials and incomplete MFA coverage

• 79% of ransomware incidents began with an identity-based approach.
• Malicious email and phishing together accounted for 50% of ransomware incidents; compromised credentials accounted for another 23%.
• In a separate review of 661 incidents, MFA protection was absent at a relevant access point in 59% of cases.

Sources: Sophos 2026 State of Ransomware; Active Adversary Report.

TREAT: Close human-identity gaps with complete, phishing-resistant MFA

• Deploy phishing-resistant MFA, preferably passkeys or security keys, for administrators, email, remote access, finance and other high-risk workflows.
• Eliminate MFA coverage gaps across VPNs, firewall consoles, SaaS applications and legacy systems used by employees, administrators and contractors.
• Add conditional access with impossible-travel and token-theft detections; disable dormant accounts and review privileged access frequently.
• Train employees to verify unusual payment, credential and data requests through a separate trusted channel, including requests that appear to use a familiar voice or image.

4. Ransomware Recovery Still Carries a Heavy Operational Price

TRICK: Ransomware encryption and recovery costs still create major disruption

• 56% of ransomware attacks succeeded in encrypting data.
• The median ransom payment was $769,000, while average recovery cost excluding the ransom reached $1.7 million.
• Only about one in three organizations stopped an attack before attackers encrypted files.

TREAT: Prove restoration capability before an attack

• Maintain immutable, offline or logically isolated backups and separate backup administration from production administration.
• Test restoration of critical systems and data, not just backup completion, and document recovery dependencies and sequencing.
• Know your legal, insurance, forensics, communications and law-enforcement decision paths. Do not improvise them during a crisis.

5. Third-Party and Software Supply Chains Expand the Attack Surface

TRICK: Third parties extend compromise into critical operations

• Third-party involvement in breaches rose 60% year over year and reached 48% of breaches.
• Attackers are compromising a single trusted supplier or software component to gain access to many connected organizations at once.

Sources: Verizon 2026 DBIR; NIST SP 1305.

TREAT: Manage suppliers as part of the enterprise attack surface

• Tier suppliers by data access, connectivity, operational dependency, substitutability and concentration risk.
• Write minimum security requirements into contracts.
• Monitor critical suppliers between assessments and connect supplier findings to incident response, business continuity and procurement decisions.
• Maintain a current inventory of externally hosted services and software components needed to deliver critical business processes.

6. Cybersecurity Should Be Governed as Business Risk

TRICK: Technical activity can obscure material business risk

• The estimated global average cost of a data breach was $4.99 million, a 12% year-over-year increase.
• Cyber risks described only in technical terms often cloud leaders from seeing which threats could disrupt critical operations, trigger regulatory exposure or cause material financial loss.

Sources: IBM 2026 Cost of a Data Breach; NIST CSF 2.0.

TREAT: Govern cyber risk through outcomes and accountable decisions

• Assign executive ownership and board oversight based on business impact, not just technical severity.
• Report a decision-useful and concise set of outcome metrics.
• Link cyber scenarios to operational, financial, legal, compliance and reputational consequences so leaders can make informed risk-acceptance decisions.
• Review cyber insurance against actual response costs, exclusions, notification duties and control conditions.

7. Effective Awareness Shifts from Annual Training to Behavior Change

TRICK: Annual training cannot match multi-channel manipulation

• Current attack patterns combine malicious email, phishing, mobile messaging, voice impersonation, stolen credentials and deepfakes.
• Attackers now move from email to text, collaboration tools or voice calls, bypassing employees who were trained to recognize suspicious messages in only one channel.

TREAT: Build verification and reporting into everyday behavior

• Use short, role-based learning tied to real workflows for executives, finance, HR, IT administrators, developers and customer-facing teams.
• Run simulations across email, text, collaboration tools and voice-based scenarios, then coach rather than shame users.
• Measure reporting speed, repeat susceptibility, verification behavior and reduction in risky actions, not just training completion alone.
• Make reporting frictionless with a prominent button or channel and give employees feedback when they report suspicious activity.

8. Workload Identities, SaaS Tokens and Cloud Evidence Require Dedicated Controls

TRICK: Workload credentials and SaaS tokens cross service boundaries while forensic evidence expires

• Identity compromise was a factor in 83% of cloud and SaaS compromises.
• Attackers’ exploitation windows have decreased so that newly exposed cloud weaknesses are being attacked within days or less of discovery, while short-lived or scattered forensic evidence may disappear before responders can reconstruct what happened.
• Attackers are taking advantage of long-lived service-account keys and SaaS tokens remaining active after systems, integrations or owners change, leaving a quiet path from attackers across connected services.

TREAT: Govern workload identities and preserve cloud forensic evidence

• Use least privilege, short-lived credentials and automated rotation for service accounts, workload identities, API keys and SaaS tokens.
• Centralize cloud control ownership and administration.
• Test evidence collection from cloud control planes, containers, serverless services and SaaS audit logs before an incident.

9. Missing Telemetry Can Turn an Incident into a Blind Spot

TRICK: Short retention and missing logs erase the attack trail

• Missing logs caused by retention gaps doubled year over year in incident datasets.
• Firewall defaults were a significant contributor, with retention sometimes limited to seven days or even 24 hours.

Source: Sophos 2026 Active Adversary Report.

TREAT: Preserve reliable telemetry and rehearse evidence-driven response

• Define minimum logging and retention standards by system criticality, threat model and investigation need.
• Monitor telemetry coverage, ingestion success, retention compliance and unauthorized changes to audit settings; alert owners when any critical source stops reporting or falls below its approved retention threshold.
• Rehearse investigations using retained evidence and document blind spots that require remediation.

10. Cryptographic Readiness Is Becoming a Business Continuity Issue

TRICK: Hidden cryptographic dependencies create long-term exposure

• Only 37% of breached organizations encrypted sensitive data both at rest and in transit.
• Only 34% had visibility into their cryptographic assets, underscoring the difficulty of locating vulnerable cryptography and planning an efficient migration.

Source: IBM 2026 Cost of a Data Breach.

TREAT: Inventory cryptography and build a migration-ready architecture

• Inventory cryptographic algorithms, keys, certificates, libraries and dependencies across critical services.
• Classify data by confidentiality and prioritize systems exposed to harvest-now, decrypt-later risk.
• Build crypto-agility into architecture, procurement and modernization plans.

From Insight to Action

These ten risks highlight a common challenge for organizations: turning technical vulnerabilities into prioritized action, clear accountability, and measurable resilience. As you plan for 2027 and beyond, focus on the following priorities:

• Patch with purpose.
• Protect human identity.
• Govern AI before it scales.
• Manage third-party dependency risk.
• Measure outcomes.
• Preserve cloud evidence.
• Protect the investigation trail.
• Prepare cryptography for change.
