Before signing, ask for evidence of its foundational cyber controls, resilience, incident process, supply-chain dependencies, equipment responsibilities, and ownership or control information. Then put important promises into the contract and decide how you will verify them over time. The framework below adapts U.S. government guidance for a proportionate business review; it does not certify any particular provider or plan as secure.
Why provider security belongs in your procurement decision
Your provider operates infrastructure that can affect connectivity, traffic paths, customer-premises equipment, support channels, and the availability of your business applications. A compromise or prolonged outage may therefore create operational and security consequences even when your own endpoints are well managed. The issue is not whether a provider can advertise a security framework. The issue is whether it can explain the controls, people, suppliers, equipment, and commitments that apply to the service you are buying.

A joint guide from CISA, NSA, the FBI, and international cyber authorities, published December 4, 2024, describes compromises of major global telecommunications providers during a cyber-espionage campaign. Its engineering and defender focus means a small business cannot independently verify every recommendation, but it demonstrates why communications infrastructure and its supply chain deserve due diligence. Read the CISA communications-infrastructure hardening guidance for that context.

#1 Best Overall
Use a five-part supplier assessment
NIST’s Cybersecurity Supply Chain Management: Due Diligence Assessment Quick-Start Guide, published July 8, 2026, organizes ICT-supplier due diligence around five components. Use them as prompts for an evidence-based conversation rather than as a pass/fail certification. The guide is available from NIST.
1. Foreign ownership, control, or influence (FOCI)
Ask which entities own, control, or materially influence the provider and the parts of the service that handle your traffic or equipment. Also ask whether significant subcontractors or equipment suppliers have ownership or control relationships that create a material risk for your organization. The purpose is to understand who may influence decisions, access systems, or be subject to another jurisdiction’s requirements.
This is not a demand for sensitive personal information or a government-style investigation. Request the level of ownership and control information the provider can lawfully and reasonably disclose, identify any material changes that would trigger notice, and document unresolved uncertainty. A provider that cannot disclose details should explain the limitation and the mitigation it uses instead.
2. Provenance
Provenance means understanding where important equipment, software, and services originate and how the provider tracks them. Ask for the material suppliers supporting the connection, gateway, authentication, monitoring, and support functions. Ask how the provider records dependencies, evaluates changes in those dependencies, and responds if a supplier becomes unavailable or untrustworthy.
You may receive a high-level supplier description rather than a complete list. Record exactly what is covered, what is withheld, the date of the information, and whether it applies to your geographic location and plan. Provenance information is useful only when its scope is clear.
3. Resilience
Resilience covers the provider’s ability to continue or restore service during equipment failures, cyber incidents, physical disruptions, and supplier problems. Ask how it designs redundancy, monitors critical systems, tests continuity, and prioritizes restoration. Request the service-level definitions that matter to you: outage measurement, escalation route, restoration target, maintenance notification, and any exclusions.
Do not assume that a published uptime percentage answers these questions. A useful response explains what is redundant, which locations or components share a dependency, how incidents are escalated, and what evidence exists that recovery arrangements are exercised.
Rank #2
4. Foundational cyber practices
Ask the provider to describe its security governance and baseline controls. Depending on what it can share, this may include a current security overview, an independent assurance report, a certification, penetration-test summary, vulnerability-management description, or risk-management framework. For every document, record its issue date, service scope, systems covered, exclusions, and whether an independent party assessed it.
A framework name or certificate is not proof that the particular internet service is secure. A document may cover corporate systems but exclude the broadband platform, customer-premises equipment, or a regional subsidiary. Ask the provider to map the evidence to the service and to identify compensating controls where the evidence does not apply.
5. Supply-chain tiers
Map the layers behind the connection: the provider, network and equipment vendors, data-center or cloud services, support partners, field contractors, and other material subcontractors. Ask how the provider identifies critical tier-two and tier-three dependencies, imposes security requirements, receives incident notifications, and verifies that those requirements are followed.
You do not need every commercial name to make a decision. You do need to know whether a critical function depends on a single undisclosed party, whether the provider can reach that party during an incident, and whether changes in important tiers will be communicated.

Send the same question set to every candidate. Written answers are easier to compare than sales demonstrations. Ask the provider to identify the accountable team, the evidence available, its date and scope, and any limitations.
Clarify service scope and responsibility
- Which legal entities operate, monitor, support, and maintain this service?
- Which controls are managed by the provider, by named subcontractors, and by the customer?
- Who administers the installed modem, gateway, or router?
- Who applies firmware, operating-system, and security updates to that equipment, and on what schedule?
- Can the customer disable remote administration, change credentials, view logs, or replace the equipment?
- Which security functions are outside the internet plan, such as managed firewalling, filtering, backup connectivity, or incident response?
These questions prevent a common failure: assuming that equipment supplied or installed by the carrier is fully managed and secured by the carrier. The contract should identify the handoff between provider and customer.
Request evidence of foundational controls
- What security governance and risk-management practices apply to the service?
- Can the provider share a current assurance report or certification, including scope, date, exclusions, and the assessing organization?
- How are privileged accounts protected and reviewed?
- How are vulnerabilities identified, prioritized, remediated, and tracked to closure?
- How are employees, contractors, and support partners trained and monitored?
- How are logs retained, protected, and made available for an investigation involving the service?
Request evidence that is specific enough to evaluate, but do not demand confidential network diagrams or information whose disclosure would itself create risk. If the provider cannot share a report, ask for a written control summary, an independent attestation letter, or a mutually acceptable verification method.
Ask about supply chain and provenance
- Which suppliers provide material network, customer-premises, authentication, monitoring, and support functions?
- How does the provider assess supplier security before onboarding and during the relationship?
- How are critical dependencies and single points of failure recorded?
- What information about equipment origin, ownership, control, and maintenance can be disclosed?
- How does the provider manage a supplier compromise, recall, sanctions issue, or sudden loss of access?
Test incident and vulnerability handling
- How can a customer report a suspected vulnerability or security incident?
- Is there a 24-hour escalation route, and who receives a report outside normal support hours?
- What events trigger customer notification?
- What are the target times for acknowledgement, updates, containment, and restoration?
- Will the provider preserve relevant logs and cooperate with the customer’s investigation?
- How will the provider notify customers about material security changes to the network or supplied equipment?
Ask for the process in writing, not merely a general support telephone number. A useful procedure identifies severity categories, escalation authority, communication channels, and the information a customer should provide.
Separate carrier controls from your local network
The provider’s backbone and operational systems are only one part of your exposure. Your premises router, Wi-Fi, endpoints, identities, applications, backups, and incident plan remain your responsibility unless the agreement clearly assigns a control to the provider.
The Federal Trade Commission’s small-business guidance recommends changing router default credentials, turning off remote management when it is not needed, using WPA2 or WPA3 wireless encryption, limiting which devices can connect, and separating guest Wi-Fi from the business network. It also recommends timely software updates, multifactor authentication, backups, and a business incident-response plan. Follow the FTC small-business cybersecurity guidance, then confirm who performs each task when the provider supplies the equipment.
Checklist for provider-supplied equipment
- Record the exact modem, gateway, or router model and firmware version at installation.
- Change every default administrator username or password, or obtain written confirmation that the provider has done so and that you can use a unique customer credential.
- Disable remote administration unless it is required for the service. If it is required, ask which source addresses, authentication controls, logging, and support procedures protect it.
- Enable WPA2 or WPA3 encryption and use a strong, unique wireless passphrase.
- Create a separate guest network and prevent guest devices from reaching business systems.
- Confirm how updates are tested, approved, deployed, and rolled back when an update causes an outage.
- Restrict management access to authorized devices and administrators, and enable multifactor authentication where the equipment supports it.
- Document how to export configuration and logs, restore a known-good configuration, and replace the device if it fails.
A business Wi-Fi router with current WPA3 support and configurable administrative controls can improve local network security, but buying one does not evaluate or secure the provider’s internal network. Treat the device as one control in your environment, not as evidence about the carrier.
Use current threat guidance without overclaiming
The December 4, 2024 communications-infrastructure guide from CISA and partner agencies is primarily for network engineers and defenders. Use it to explain why visibility, hardening, monitoring, and supply-chain questions matter, not as a checklist that a small customer can independently validate.
A separate CISA alert dated June 18, 2024 discusses Zero Trust, Secure Service Edge, and Secure Access Service Edge approaches, along with risks from misconfigured remote access. These are architectures for securing your organization’s access to applications and networks. They are not guarantees about a broadband provider. Read the CISA network-access alert when deciding how your own users and devices should connect, while keeping that decision separate from provider due diligence.
Compare providers with one scorecard
For two or more candidates, create one record per provider. Do not award a positive score for an unanswered question. Preserve the original response, evidence file or link, publication date, scope, responsible party, and any contractual commitment. A simple comparison structure is:
Rank #4
| Comparison axis | What to record |
|---|---|
| Foundational cyber practices | Documented governance and baseline controls; evidence type, scope, exclusions, and recency |
| Resilience and incident handling | Continuity design, escalation contact, notification triggers, response targets, and restoration commitments |
| Supply-chain transparency | Material subcontractors and dependencies, supplier-risk process, and available provenance information |
| Equipment and responsibility | Who administers, updates, logs, and secures the gateway or router and the provider network |
| Verification and contract | Security terms, assurance or audit evidence, notice obligations, remedies, and review process |
Mark each item as documented, partially documented, unanswered, or not applicable, and explain why. Then assess the business impact of each unknown. For example, an unclear update process for a carrier-managed gateway may require a written commitment before installation; an undisclosed low-risk subcontractor may call for clarification but not necessarily disqualify the service.
This scorecard synthesizes NIST’s ICT-supplier categories with FTC guidance on supplier contracts and verification. The FTC’s warning is direct: “Security can’t be a ‘take our word for it’ thing.” The quotation appears in Start with Security: A Guide for Business.

Turn important answers into contract terms
FTC business guidance recommends assessing suppliers before contracting, writing security expectations into vendor agreements, verifying compliance, and keeping controls current. Apply that advice to the controls the provider actually manages; it is general vendor guidance, not a telecom-specific certification.
Ask your legal and security contacts to convert material expectations into terms such as:
- A defined description of the service, equipment, locations, and provider or subcontractor responsibilities.
- Minimum security practices for provider-managed systems and customer-premises equipment.
- Patch and vulnerability-remediation expectations, including treatment of critical issues.
- Incident notification triggers, timeframes, escalation contacts, cooperation duties, and evidence preservation.
- Maintenance and material-change notice requirements.
- Continuity, restoration, and service-credit terms that match your operational needs.
- Rights to receive current assurance information or use an agreed independent verification process.
- Notice of material ownership, control, or critical-subcontractor changes.
- Exit assistance, equipment return or replacement, configuration export, and secure deletion or retention obligations.
Do not copy a generic security schedule without checking whether the provider can perform it. Each obligation should have an accountable party, a measurable trigger or deliverable, and a method for resolving noncompliance.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Verify after selection
Due diligence is not complete when the order is signed. Establish a review cadence based on risk and service criticality. At each review:
- Confirm that the service, equipment models, support entities, and subcontractors still match the contract.
- Request updated assurance evidence and note any changed scope, exclusions, or expired reports.
- Review incidents, outages, vulnerability notifications, maintenance records, and unresolved corrective actions.
- Test the escalation contact and verify that your own contact list is current.
- Check gateway firmware, administrative settings, wireless encryption, guest isolation, backups, and multifactor authentication.
- Reassess whether new applications, locations, remote workers, or regulatory obligations change the required controls.
Keep a dated decision record. It should show what you knew when you selected the provider, which risks you accepted, which commitments you obtained, and who owns follow-up actions.
Red flags and practical responses
Only a framework logo or certificate is offered
Request the actual scope, date, exclusions, and relationship to your service. If the provider cannot show that the evidence covers the relevant platform, treat the claim as limited rather than as proof.
The provider refuses all operational detail
Some network details are legitimately sensitive. Ask for a control summary, independent assurance, defined incident commitments, and a confidential review process instead of secret diagrams. If the provider will not provide even those alternatives, record the uncertainty and weigh its business impact.
Responsibility for the gateway is unclear
Do not install the service until the agreement identifies who administers the device, applies updates, controls remote access, supplies logs, and replaces faulty equipment. Assign any remaining tasks internally.

Incident notification is limited to “service outages”
Ask whether unauthorized access, data exposure, malicious firmware, or a supplier compromise can occur without a complete outage. Define security-event notification separately from availability reporting.
Answers are verbal or change between departments
Send a written recap and ask the provider to confirm it. Preserve the version, date, and respondent. Only treat a promise as durable when it is incorporated into the agreement or another signed document.
A decision sequence you can reuse
- Define the service boundary. List locations, connection types, provider equipment, managed services, critical applications, and required availability.
- Send the common questionnaire. Cover FOCI, provenance, resilience, foundational practices, supply-chain tiers, incidents, vulnerabilities, and equipment responsibility.
- Examine evidence. Check date, scope, exclusions, assessor, and applicability to the plan and region you will buy.
- Investigate gaps. Ask follow-up questions and label each unresolved item instead of assuming a favorable answer.
- Compare consistently. Use the same scorecard, retain source documents, and assess the business impact of unknowns.
- Negotiate commitments. Put material controls, notifications, verification, continuity, and exit duties into the contract.
- Validate implementation. Check the installed equipment and local controls before production use.
- Review continuously. Recheck evidence, incidents, suppliers, ownership, equipment, and your own risk as circumstances change.
This process produces a defensible procurement decision without pretending that a customer can inspect a carrier’s entire network. It also makes the division between provider-managed security and customer-managed security explicit.
What a strong answer looks like
A credible provider response is specific about scope and accountable parties. It identifies the evidence available, its date and exclusions, the process for vulnerabilities and incidents, the dependencies that matter, and the commitments it will sign. It explains what cannot be disclosed and offers a reasonable alternative verification method. It also states exactly how a supplied gateway is administered and updated.

Those deficiencies do not automatically prove insecurity, but they increase uncertainty. Compare that uncertainty with your business’s tolerance for outage, unauthorized access, delayed notification, and difficult recovery before choosing.
