9 Top Security Risks and Tools for Private Clubs Managing Member Data, Payments and Vendor Access (2026)

Private clubs depend on a surprisingly complex mix of technology. Member records, payments, POS systems, reservations, accounting, Microsoft 365, access control, employee devices, guest Wi-Fi and outside vendors may all connect to daily operations.

For a GM, Controller or club leader, the real security challenge is not simply worrying about “cybersecurity.” It is knowing who can access important systems, whether member and payment information is properly protected, and whether the club could continue operating if a system, account or vendor connection failed.

The nine areas below focus on the practical risks club leaders can identify, question and manage.

Criteria

The nine items were selected using four criteria:

• Operational impact: Could the issue interrupt payments, dining, reservations, communications, accounting or other club operations?
• Data exposure: Could it affect member, employee, financial or payment information?
• Likelihood of being overlooked: Can the risk grow quietly as employees, vendors and systems change?
• Ability to address it: Is there a practical combination of technology, process or accountability that can reduce the risk?

The order is intended as a practical starting point, not a universal ranking. Every club’s priorities will depend on its systems, vendors, payment environment and existing controls.

1. Payment Systems Where Responsibility Is Not Clear

Private clubs may accept payments through dues, dining, golf shops, events, online statements, mobile POS and other channels. Even when a third party processes those transactions, the club still has responsibilities.

The PCI Security Standards Council states that outsourcing payment processing does not remove a merchant’s responsibility to oversee applicable service providers, understand shared responsibilities and validate compliance as required. PCI DSS also requires organizations using applicable third-party service providers to monitor their PCI compliance status at least annually.

What to check

• Who processes each type of payment?
• Where can staff enter or view payment information?
• What PCI responsibilities belong to the club?
• Which responsibilities belong to the payment provider?
• Who owns the club’s annual PCI validation process?

Tools and controls to consider

• Tokenized payment processing
• Point-to-point encryption, or P2PE, where appropriate
• The applicable PCI DSS Self-Assessment Questionnaire
• Approved external vulnerability scanning where required

For applicable environments, PCI DSS requires vulnerability scans at least once every three months.

Private-club platforms such as Clubessential and Jonas Club Software also address payment security. Clubessential states that CE Payments encrypts and tokenizes sensitive payment data. Jonas specifically notes that using its payment technology does not eliminate a club’s PCI reporting responsibilities.

2. Vendors That Still Have Access After Their Work Is Done

Clubs often rely on different companies for club-management software, POS, cameras, access control, HVAC, accounting applications, networks, websites and other systems.

Vendor access is often necessary. Unmanaged vendor access is the problem.

Questions a club should be able to answer

• Which vendors currently have remote access?
• Which systems can each vendor reach?
• Does each technician have an individual account?
• Is multifactor authentication required?
• Who approves vendor access?
• Is access removed when a project or relationship ends?

Tools and controls to consider

• Microsoft Entra ID for identity and access management
• Cisco Duo for multifactor authentication
• Privileged-access products such as BeyondTrust or CyberArk for environments that warrant more formal controls
• A vendor-access register listing vendor, system, access method, owner and review date

Before adding another product, clubs should first create visibility. If leadership cannot identify who has remote access to critical systems, that is the first problem to solve.

3. Shared Accounts and Employee Access That Never Gets Cleaned Up

Private clubs frequently have shared workstations, multiple departments and employees who change roles. Seasonal or temporary staff can add another layer of complexity.

A shared account such as frontdesk@ or a generic administrative login may be convenient, but it makes accountability and offboarding harder.

Tools and controls to consider

• Individual employee accounts wherever systems support them
• Role-based access based on job responsibilities
• A formal onboarding and offboarding checklist
• Microsoft Entra ID, Microsoft Authenticator or Cisco Duo
• Password managers such as NordPass, Keeper or Bitwarden Business when credentials legitimately need to be shared

Multifactor authentication is one of the strongest baseline controls available. Microsoft reports that MFA can block more than 99.2% of identity-based attacks.

For systems within applicable PCI DSS scope, PCI DSS v4.x also requires passwords used as an authentication factor to be at least 12 characters, or at least eight characters if the system does not support 12.

A useful test is simple: Can you remove one employee’s access without changing everyone else’s login?

4. Too Many People Can Access Too Much Member Information

Member information may exist across club-management systems, accounting software, Microsoft 365, SharePoint, shared drives and other applications.

Depending on the club, that may include:

• Member contact information
• Account balances and transaction history
• Reservation and event activity
• Family or household information
• Financial reports
• Employee records
• Board documents

The issue is often not that the software lacks permissions. It is that permissions accumulate.

An employee changes jobs but keeps old access. A consultant receives temporary access that becomes permanent. A Microsoft 365 group grows without anyone reviewing who still belongs in it.

Tools and controls to consider

• Role and permission controls within Jonas, Clubessential or other core applications
• Microsoft Entra ID groups for managing access
• Microsoft Purview when more formal data classification or loss-prevention controls are appropriate
• Recurring access reviews for finance, HR, executive and member-data systems

The objective should be least-necessary access: employees can reach what they need for their jobs without automatically seeing everything the club stores.

5. Guest Wi-Fi, POS and Business Systems Are Not Properly Separated

A private club may provide connectivity across a clubhouse, dining areas, golf shop, pool, fitness facilities, event spaces and outdoor areas.

That makes network design both an operational and security issue.

Member and guest devices should not have unnecessary access to payment, accounting or administrative systems.

The PCI Security Standards Council notes that network segmentation can reduce which systems fall within the cardholder data environment. Poor segmentation can expand that scope.

Networks to evaluate separately

• Guest and member Wi-Fi
• Employee devices
• POS and payment systems
• Administrative systems and servers
• Cameras, access control and other connected devices

Tools commonly used for business-grade networking

• Cisco Meraki
• HPE Aruba
• Fortinet

The specific product is less important than the configuration. Having two different Wi-Fi names does not, by itself, prove the underlying systems are properly isolated.

6. Emails and Texts That Look Like Normal Club Business

Private clubs operate through relationships. Employees communicate constantly with members, vendors, board members and coworkers, giving fraudulent messages plenty of believable context.

A fake request could look like:

• A vendor changing payment instructions
• A GM requesting a document
• A board member asking for information
• A member questioning a charge
• A Microsoft sign-in notification
• A text about a delivery or reservation

In phishing simulations analyzed in Verizon’s 2026 Data Breach Investigations Report, the median successful click rate for mobile-focused tactics such as voice and text messages was 40% higher than for email.

Tools and controls to consider

• Microsoft Defender for Office 365
• Check Point Harmony Email & Collaboration, formerly Avanan
• Proofpoint
• MFA
• Employee security-awareness training
• A verification process for changes to banking or payment instructions

Technical filtering matters, but so does making it normal for employees to verify an unusual request before acting.

7. Internet-Facing Technology Is Not Patched Quickly Enough

Security risk is not limited to stolen passwords.

Verizon’s 2026 DBIR reports that 31% of breaches started with exploitation of software vulnerabilities, making vulnerabilities the leading initial-access method in its dataset.

For a private club, technology requiring updates can extend beyond employee computers.

Systems to include

• Firewalls
• VPN or remote-access systems
• Servers
• Wireless equipment
• Websites and applications
• Cameras and connected devices
• Employee computers
• Older software that may no longer receive security updates

Tools and controls to consider

• Microsoft Intune
• NinjaOne
• Automox
• Automated operating-system and application patching
• Vulnerability scanning
• A replacement plan for unsupported equipment

The management question is not simply, “Do we patch computers?” It is, “Who is responsible for identifying every system that needs to be updated?”

8. Backups Exist, but Nobody Knows How Recovery Would Actually Work

Having a backup is not the same as having a recovery plan.

A club should know what would happen if an important system became unavailable during a busy weekend, event or accounting cycle.

Verizon reports that ransomware was involved in 48% of breaches analyzed in its 2026 DBIR.

Rather than focusing only on the threat itself, club leaders should ask what happens after an outage.

Questions to answer

• Which systems and data are backed up?
• How frequently?
• How long are backups retained?
• Can an attacker or compromised administrator delete them?
• Who is responsible for restoring data?
• When was a real restore last tested?
• Which systems must return first?

Backup platforms may include

• Veeam
• Datto
• Cove Data Protection
• Dedicated Microsoft 365 backup products

The tool is only one piece. The club also needs recovery priorities for accounting, member communications, files, payments and other essential functions.

9. Employees Are Using AI Without Clear Rules for Club Information

AI is becoming part of everyday work. Club teams may use tools to draft member communications, summarize meeting notes, analyze spreadsheets, prepare presentations or streamline administrative tasks.

The security issue is not simply whether employees use AI. It is whether anyone has established rules for what information can be entered into those systems.

Information that deserves clear handling rules

• Member lists
• Individual member situations
• Financial statements
• Payroll and HR information
• Board documents
• Credentials
• Payment information
• Confidential contracts

Verizon’s 2026 DBIR found that threat actors are also using generative AI across different stages of attacks, including targeting, initial access and malware development. The report found a median threat actor researched or used AI assistance across 15 different documented techniques.

Tools and controls to consider

• A written acceptable-AI-use policy
• Approved business platforms such as Microsoft 365 Copilot or ChatGPT Business
• Data-loss-prevention controls where appropriate
• Employee training on what information should not be entered into unapproved AI systems

Clubs do not need an overly complicated AI policy to begin. Employees do need to know which tools are approved, what information is restricted and whom to ask when they are unsure.

How to Choose Which Security Improvements Come First

Do not begin by purchasing nine new security products. Begin by determining where the club has the greatest combination of operational importance, sensitive information and unclear ownership.

Step 1: Identify critical systems

Map the systems responsible for:

• Member information
• Payments and POS
• Accounting and finance
• Email and Microsoft 365
• Reservations and club operations
• Access control
• Network connectivity

Step 2: Identify who has access

For each system, document:

• Employees with access
• Administrative accounts
• Outside vendors
• Remote-access methods
• Other systems connected to it

Step 3: Score each area using five questions

For every critical system, ask:

1. Is MFA required where available?
2. Can access be removed quickly?
3. Is the technology patched and supported?
4. Can the data or system be recovered?
5. Is one person or provider clearly accountable for managing it?

The areas with the most “no” or “we don’t know” answers should move toward the top of the priority list.

FAQ

Does our club still have PCI responsibilities if Jonas, Clubessential or another company processes our payments?

Yes. Outsourcing payment processing can reduce the systems and PCI requirements that apply directly to the club, but it does not automatically eliminate the club’s responsibilities.

PCI SSC says merchants using third parties still need to oversee relevant providers, understand shared responsibilities and monitor applicable providers’ PCI compliance status at least annually.

Confirm your specific validation requirements with your acquiring bank, payment brand or appropriate PCI resource.

Should member Wi-Fi be separate from our staff and POS systems?

Member and guest devices should be appropriately isolated from systems they do not need to access, particularly payment and administrative environments.

The exact design depends on the club, but PCI guidance makes clear that network segmentation can affect which systems fall within the cardholder data environment.

Do not assume separate Wi-Fi names automatically mean the underlying networks are securely separated.

Do all club employees need MFA?

MFA should be broadly used on business systems that support it, with particular priority given to email, Microsoft 365, remote access, administrative accounts and systems containing sensitive information.

Microsoft reports that MFA can block more than 99.2% of identity-based attacks.

The exact implementation will depend on each application and the types of accounts employees use.

Can I use this plugin with Elementor, WPBakery, or other page builders?

Yes, the Advanced Accordion Block works seamlessly with Gutenberg and can be used inside Elementor using the Gutenberg widget. It is also compatible with WPBakery, Beaver Builder, and Divi, though in these builders, you may need to use shortcodes or embed the accordion within custom HTML blocks. To ensure smooth performance, keep your page builder and WordPress version up to date.

How often should we review vendor access?

Review access whenever a vendor relationship or project ends, and establish a recurring review for vendors with remote or administrative access.

For applicable payment-related third parties, PCI DSS requires organizations to monitor service providers’ PCI compliance status at least annually.

What should we do first if we do not know how secure our club’s technology is?

Do not start by shopping for another product.

Start by inventorying:

• Critical systems
• Administrative accounts
• Vendors with access
• Payment systems
• Network connections
• Backup and recovery responsibilities

Then determine where MFA is enabled, which vendors have remote access, how critical systems are separated and who owns each responsibility.

Once those basics are visible, leadership can prioritize actual gaps instead of guessing.
