15 Enterprise Security and Compliance Gaps Your Organization Needs to Close Before the End of 2025
Why This Checklist Exists
The regulatory and threat landscape that enterprise IT teams must navigate in 2025 looks materially different from what it did just eighteen months ago. The SEC's cybersecurity disclosure rules for public companies, expanded FTC Safeguards Rule enforcement, updated HIPAA guidance, and the continued rollout of state-level privacy legislation have collectively raised compliance obligations for organizations of virtually every size.
At the same time, threat actors have grown more sophisticated, automated, and persistent. The mid-market—companies with between 100 and 2,500 employees—has become a preferred target precisely because these organizations hold valuable data but often lack the security infrastructure of larger enterprises.
The fifteen items below represent the gaps most commonly identified during enterprise IT assessments of SMB and mid-market organizations operating in the United States. Each entry includes what to look for, why it matters under current regulatory and threat conditions, and a practical starting point for remediation.
1. Unpatched Operating Systems and Applications
What to look for: Systems running end-of-life operating systems (Windows Server 2012, for example) or applications that have not received security patches within the last 30 days.
Why it matters: Unpatched systems represent the most consistently exploited attack vector in enterprise environments. CISA's Known Exploited Vulnerabilities catalog continues to grow, and attackers actively scan for unpatched endpoints.
Quick fix: Implement automated patch management through a centralized endpoint management platform. Establish a documented patch cadence with defined SLAs for critical, high, and medium severity updates.
2. Absence of Multi-Factor Authentication on Critical Systems
What to look for: Administrative accounts, VPN access, email platforms, and cloud consoles that authenticate with passwords alone.
Why it matters: Credential theft remains the leading initial access method in enterprise breaches. MFA eliminates the majority of password-based attack scenarios. Post-2024 cyber insurance underwriters now frequently require MFA documentation as a condition of coverage.
Quick fix: Enforce MFA across all privileged accounts and externally accessible systems immediately. Microsoft Authenticator, Duo, and similar solutions deploy quickly in most environments.
3. Overprivileged User Accounts
What to look for: Standard users with local administrator rights, service accounts with domain admin privileges, or employees with access to systems beyond their role requirements.
Why it matters: The principle of least privilege limits lateral movement during a breach. Overprivileged accounts transform a contained incident into an enterprise-wide compromise.
Quick fix: Conduct an access rights review. Revoke local admin rights from standard users and implement Privileged Access Management (PAM) for administrative credentials.
4. Missing or Untested Data Backup Procedures
What to look for: Backup schedules that have not been verified through restoration testing, single-location backups, or backup systems connected to the primary network.
Why it matters: Ransomware operators specifically target backup infrastructure. Without verified, isolated backups, recovery from a ransomware event may be impossible without paying the ransom.
Quick fix: Adopt a 3-2-1 backup strategy (three copies, two media types, one offsite or air-gapped). Test restoration procedures quarterly and document results.
5. No Formal Incident Response Plan
What to look for: Organizations that have never documented what happens when a security incident occurs—who is notified, who makes decisions, and what steps are followed.
Why it matters: SEC cybersecurity disclosure rules now require public companies to report material incidents within four business days. Even private companies face state-level breach notification obligations. Without a plan, response time and cost increase dramatically.
Quick fix: Develop a written Incident Response Plan aligned to NIST SP 800-61. Conduct a tabletop exercise with key stakeholders at least annually.
6. Insufficient Endpoint Detection and Response Coverage
What to look for: Endpoints protected only by traditional antivirus software, or EDR solutions deployed on fewer than 100 percent of managed devices.
Why it matters: Signature-based antivirus does not detect modern fileless malware, living-off-the-land attacks, or zero-day exploits. EDR provides the behavioral detection and forensic visibility that incident response requires.
Quick fix: Evaluate and deploy an EDR solution across all managed endpoints. Ensure coverage includes servers, not just workstations.
7. Unmanaged or Untracked Third-Party Vendor Access
What to look for: Vendors, contractors, or managed service providers with persistent network access that is not regularly reviewed or time-limited.
Why it matters: Third-party access is a primary vector for supply chain attacks. The updated NIST Cybersecurity Framework 2.0 places explicit emphasis on supply chain risk management.
Quick fix: Inventory all third-party access credentials. Implement just-in-time access provisioning and require vendors to complete a security questionnaire annually.
8. No Network Segmentation
What to look for: Flat network architectures where all devices—servers, workstations, printers, IoT devices—reside on the same network segment.
Why it matters: Flat networks allow attackers unrestricted lateral movement once initial access is achieved. Segmentation contains breaches and limits damage.
Quick fix: Separate critical systems, guest networks, and operational technology onto distinct VLANs with firewall rules controlling inter-segment traffic.
9. Gaps in Employee Security Awareness Training
What to look for: Organizations that conduct security training once per year at onboarding, or not at all. No phishing simulation program in place.
Why it matters: Social engineering remains the most effective attack technique. The FTC Safeguards Rule specifically references employee training as a required element of an information security program.
Quick fix: Implement quarterly security awareness training and monthly phishing simulations. Track click rates and provide targeted remediation for repeat offenders.
10. Undocumented Software Asset Inventory
What to look for: No authoritative record of what software is installed across the enterprise, including versions, license status, and end-of-life dates.
Why it matters: You cannot protect what you cannot see. Software asset management is a foundational control in CIS Controls v8 and a prerequisite for effective vulnerability management.
Quick fix: Deploy a software asset management tool integrated with your endpoint management platform. Establish a process for reviewing new software installations.
11. Misconfigured Cloud Storage Permissions
What to look for: Publicly accessible S3 buckets, Azure Blob containers, or Google Cloud Storage objects containing sensitive business data.
Why it matters: Cloud misconfiguration remains one of the leading causes of data exposure incidents. Many organizations have never audited their cloud storage access controls after initial deployment.
Quick fix: Use cloud-native security posture management tools (AWS Security Hub, Microsoft Defender for Cloud) to identify and remediate publicly accessible storage resources.
12. No Formal Data Classification Policy
What to look for: Organizations that treat all data identically, with no documented framework for categorizing sensitive, confidential, or regulated information.
Why it matters: Effective data protection requires knowing what data exists, where it lives, and what controls apply to it. State privacy laws including CCPA, VCDPA, and CPA require organizations to understand their data inventory.
Quick fix: Develop a data classification policy with at minimum three tiers (public, internal, confidential/regulated) and apply appropriate handling controls to each tier.
13. Weak or Absent Email Security Controls
What to look for: Email domains without DMARC, DKIM, and SPF records configured and enforced. No anti-phishing or business email compromise protection beyond basic spam filtering.
Why it matters: Business email compromise cost US organizations more than $2.9 billion in 2023 according to FBI IC3 data. Proper email authentication significantly reduces spoofing risk.
Quick fix: Configure and enforce DMARC with a reject policy. Deploy an advanced email security gateway with BEC and impersonation detection capabilities.
14. Compliance Documentation That Has Not Been Updated Post-2024
What to look for: Information security policies, privacy notices, and vendor agreements that predate recent regulatory changes and have not been reviewed by legal or compliance counsel.
Why it matters: Regulatory enforcement actions increasingly reference the adequacy of written policies, not just technical controls. Outdated documentation creates liability exposure even when technical controls are current.
Quick fix: Schedule an annual policy review with IT, legal, and compliance stakeholders. Prioritize updates to privacy notices, acceptable use policies, and vendor data processing agreements.
15. No Defined Vulnerability Management Program
What to look for: Organizations that run vulnerability scans only when required for a compliance audit, with no defined process for prioritizing and remediating findings.
Why it matters: Vulnerability scanning without a remediation workflow produces reports, not security. A formal program connects discovery to action, with defined timelines based on severity.
Quick fix: Establish a vulnerability management program with defined SLAs: critical vulnerabilities remediated within 24 hours, high within 7 days, medium within 30 days. Assign ownership and track progress in a ticketing system.
Where to Go From Here
No organization addresses fifteen gaps simultaneously. The most effective approach is to prioritize based on a combination of risk severity and remediation effort—tackling quick wins that deliver immediate risk reduction while building a roadmap for more complex initiatives.
An honest assessment of your current posture against this checklist is a productive starting point. Organizations that approach security and compliance systematically—rather than reactively—consistently demonstrate better outcomes across both audit results and incident metrics.
If your team needs support conducting a structured IT assessment, developing a remediation roadmap, or implementing any of the controls described above, EviPC Solutions works with mid-sized businesses across the United States to simplify exactly these challenges.
