Cybersecurity audit for CPA firms and tax preparers in Orange County

01IRS WISP, tax data, Microsoft 365

CPA Firms & Tax Preparers

CPA firms and tax preparers manage Social Security numbers, tax returns, bank details, business financials, and client identity documents. That makes accounting offices high-value targets for tax data theft, business email compromise, ransomware, and fraudulent refund schemes.

OC Security Audit reviews Microsoft 365 security, email controls, MFA, backups, endpoint protection, administrative access, and IRS WISP readiness so tax practices can document risk, close gaps, and protect client data before busy season pressure makes remediation harder.

IRS WISP compliance consulting for tax preparers and accounting offices

02Written Information Security Plan

IRS WISP Compliance for Tax Preparers

Tax preparers need more than a policy template. A practical Written Information Security Plan should connect risk assessment, safeguards, access control, incident response, vendor oversight, and evidence into an operating program.

This service helps tax offices organize WISP documentation, review technical safeguards, map FTC Safeguards expectations, and build a remediation roadmap that supports client trust and regulatory readiness without overpromising guaranteed compliance.

Healthcare clinic cybersecurity and HIPAA readiness in Orange County

03HIPAA, PHI, ransomware

Healthcare Clinics

Medical clinics depend on EHR systems, Microsoft 365, billing platforms, imaging workflows, and connected devices while handling protected health information. Attackers target healthcare because downtime disrupts patient care and PHI exposure creates serious legal, operational, and reputational risk.

The review focuses on HIPAA Security Rule readiness, identity controls, email security, endpoint protection, backup recoverability, incident response, and practical evidence that clinic leaders can use to prioritize improvements.

Dental office cybersecurity, HIPAA, backups, and ransomware protection

04Dental PHI and backups

Dental Offices

Dental and orthodontic offices often rely on practice management software, imaging systems, insurance portals, email, and shared front-office workflows. A single compromised mailbox or failed backup can create serious patient-data and scheduling disruption.

OC Security Audit reviews Microsoft 365, staff awareness, ransomware readiness, backup recovery, endpoint controls, and HIPAA-aligned safeguards so dental practices can reduce risk without slowing down patient operations.

Law firm cybersecurity for confidential client records and Microsoft 365

05Client confidentiality

Law Firms

Law firms protect privileged communications, contracts, case files, settlement information, and sensitive client records. Email compromise, weak file sharing, excessive access, and remote access gaps can quickly become business, ethical, and reputational issues.

The law firm cybersecurity review evaluates Microsoft 365, secure file sharing, privileged accounts, endpoint controls, backup posture, incident response, and cyber insurance readiness so attorneys can demonstrate reasonable protection of confidential information.

Cyber insurance readiness review for MFA, EDR, backups, and incident response

06MFA, EDR, backups

Cyber Insurance Readiness

Cyber insurance applications and renewals now ask detailed questions about MFA, endpoint detection, backups, privileged access, patching, logging, and incident response. Inaccurate answers can create coverage and operational risk.

OC Security Audit helps businesses validate questionnaire responses, collect evidence, identify gaps, and build a remediation plan that supports insurance readiness and more mature security operations.

Customer security questionnaire support and evidence review

07Evidence and control mapping

Customer Security Questionnaire Support

Customers, partners, and enterprise buyers increasingly ask vendors to prove security maturity before contracts move forward. These questionnaires often cover policies, Microsoft 365, access controls, vulnerability management, incident response, and third-party risk.

This support helps businesses answer accurately, gather evidence, map controls, avoid risky overstatements, and create a remediation roadmap for gaps that could block deals or weaken customer confidence.

Ransomware readiness assessment for backups, endpoints, Microsoft 365, and response planning

08Backup recovery and containment

Ransomware Readiness

Ransomware risk is not only a malware problem. It usually involves identity compromise, exposed remote access, weak endpoint controls, missing segmentation, untested backups, and unclear response procedures.

OC Security Audit evaluates the controls that matter before an incident: MFA, backup immutability and restore testing, endpoint protection, Microsoft 365 security, firewall/VPN exposure, incident response roles, and executive reporting.

Vendor risk management consulting for SaaS, MSP, cloud, and third-party providers

09Third-party risk

Vendor Risk Management

Third-party providers often have access to systems, data, cloud platforms, support portals, and sensitive workflows. A vendor weakness can become your incident, especially when contracts and technical access controls are not aligned.

The vendor risk review covers questionnaires, evidence, SaaS access, MSP oversight, cloud provider risk, contractual security requirements, and practical risk reporting for leadership and compliance teams.

Independent security audit services for MSP clients and partner support

10Independent review

MSP Client Security Audits

MSP clients need clear security reporting that goes beyond routine IT support. Independent audits help validate Microsoft 365 controls, firewall configuration, endpoint security, vulnerability exposure, backup posture, and compliance readiness.

OC Security Audit can support MSPs and their clients with executive-friendly findings, technical remediation details, partner-friendly delivery, and practical recommendations that improve trust without creating unnecessary friction.

Manufacturing cybersecurity for OT systems, production networks, and Microsoft 365

11OT and production uptime

Manufacturing Companies

Manufacturing companies face ransomware, vendor access, legacy systems, production downtime, and sensitive business-data exposure. When office networks, Microsoft 365, remote access, and industrial systems are not segmented or monitored, operational disruption can spread quickly.

The manufacturing review looks at business networks, OT exposure, firewall rules, remote access, backup recovery, Microsoft 365 security, endpoint protection, and customer or compliance requirements tied to production reliability.

Construction company cybersecurity for project data, field teams, and cloud collaboration

12Field teams and project data

Construction Companies

Construction companies operate across offices, job sites, mobile devices, subcontractors, cloud file sharing, project management systems, and accounting platforms. That distributed workflow creates real exposure to wire fraud, stolen credentials, ransomware, and data leakage.

OC Security Audit reviews Microsoft 365 collaboration, mobile access, MFA, project and accounting system protection, subcontractor risk, backups, and ransomware readiness so construction leaders can protect active projects and financial workflows.

Engineering firm cybersecurity for CAD files, intellectual property, and client project data

13CAD and IP protection

Engineering Firms

Engineering firms manage CAD files, designs, models, project specifications, client data, and intellectual property. Weak access controls, unmanaged sharing, and compromised accounts can expose sensitive work product or delay project delivery.

The engineering cybersecurity review focuses on Microsoft 365, cloud collaboration, CAD/project file security, identity controls, vendor access, backup recovery, and practical safeguards for intellectual property protection.

Real estate cybersecurity for wire fraud prevention and secure client communications

14Wire fraud prevention

Real Estate Companies

Real estate companies are frequent targets for wire fraud and business email compromise because transactions move quickly and rely heavily on email, document exchange, and client trust. A compromised inbox can create major financial damage.

OC Security Audit reviews email security, Microsoft 365 controls, MFA, secure file sharing, mobile device practices, backup readiness, and user awareness to reduce wire-fraud and client-data risks.

Nonprofit cybersecurity for donor data, Microsoft 365, and cloud collaboration

15Donor trust and operations

Nonprofit Organizations

Nonprofits handle donor records, volunteer information, financial systems, cloud collaboration, grant documentation, and community operations, often with limited IT resources. Attackers know these organizations may have stretched budgets and informal access controls.

The nonprofit cybersecurity review prioritizes practical improvements: Microsoft 365 security, identity access, staff and volunteer awareness, backups, ransomware readiness, governance, and reporting that supports board-level risk decisions.

FAQ

Industry cybersecurity questions

Which cybersecurity page should I choose first?

Start with the industry page that best matches your business model. If your need is driven by an event such as cyber insurance renewal, ransomware concern, a vendor questionnaire, or IRS WISP documentation, use that specialized page first.

Can OC Security Audit help if we already have an IT provider?
