For defense subcontractors

IT Services for Defense Subcontractors

Your team needs to deliver contract work while protecting the information, systems, and relationships that make that work possible. When devices are unmanaged, project files live in personal drives, and access depends on shared passwords, even routine staff changes can become a security problem. Rebnetik helps defense subcontractors connect managed IT, security operations, and CMMC Level 1 and Level 2 readiness around their actual environment. Start with what your contracts require, where information travels, and who is responsible for each control. Build a practical plan before purchasing another tool or making a broad compliance claim.

Where support makes a difference

Your obligations extend beyond a checklist.

For subcontractors with a small internal IT team, an overstretched administrator, or no dedicated IT department. Support can focus on a defined project, complement your existing staff, or address ongoing management needs through an agreed scope. Whether your business uses Microsoft 365, Google Workspace, local servers, or a mixture, the starting point is the same: establish company ownership, clear accountability, and a reliable picture of what needs protection.

Risks we help you address

Replace workarounds with clear controls.

Know your assets and your information boundary

An inventory should explain more than how many laptops you own. Identify business devices, user accounts, administrators, cloud subscriptions, applications, and the people responsible for them. Then map where Federal Contract Information and Controlled Unclassified Information enter, move, and leave the business. Google Workspace can support centralized administration, but available controls depend on configuration and subscription. A cloud account alone does not create a managed environment. Rebnetik helps establish that baseline so readiness work addresses the systems in scope. An enclave may reduce exposure and assessment scope when properly designed, but it is not a shortcut around contract requirements.

Replace incident-driven changes with planned controls

Buying protection after a compromised account or failed customer review creates pressure to spend quickly. A planned approach prioritizes the gaps that matter to your operations and information boundary: account security, device configuration, patching, endpoint protection, logging, and recovery. Define who reviews alerts, who approves changes, and what happens when a control stops working. Existing response commitments remain governed by your agreement. Rebnetik can help turn one-time fixes into repeatable management activities, with an agreed sequence and ownership. The goal is a defensible operating process, supported by evidence, rather than a collection of products nobody consistently manages.

Make onboarding, offboarding, and file ownership repeatable

Every new hire should receive approved access through a documented process, and every departure should trigger timely removal of access, session review, device handling, and transfer of business records. Standardize project folders, permissions, and ownership before another employee leaves with the only usable copy. Personal OneDrive and Google My Drive have a role in individual work, but team records need appropriate company-controlled collaboration spaces, such as SharePoint and Teams document libraries or Google shared drives. Review external sharing and inherited permissions alongside the folder structure. Your information boundary and contractual obligations should guide which platform and configuration are suitable for each workload.

Give each person an identity and teach safe decisions

A password shared across the company makes access difficult to revoke and actions difficult to attribute. Business subscriptions and vendor accounts should have clear company ownership, named administrators, and appropriate individual access. Where a shared credential cannot yet be removed, document the exception and manage it through approved controls. Pair stronger authentication with practical security awareness training: checking unexpected requests, recognizing suspicious sign-in prompts, and reporting mistakes promptly. An external-email notice can provide context, but it cannot determine whether a message is safe. Training, authentication, filtering, and a usable reporting process need to work together.

Correct email and collaboration settings before they cause disruption

Misconfigured email, file servers, and collaboration tools can expose information or interrupt customer communication without an obvious warning. Review SPF, DKIM, and DMARC for your actual sending services, introduce enforcement carefully, and confirm that legitimate business mail still arrives. These controls help address domain impersonation; they do not stop every phishing message. An organization operating its own mail server also needs an appropriate filtering and maintenance plan. Review file permissions, external sharing, privileged access, and recovery alongside email. Rebnetik helps connect configuration work to a named owner and a review schedule so settings do not drift unnoticed.

Buy the capabilities you need, with clear ownership

Overlapping security tools, unused subscriptions, and unsuitable device editions can consume the budget without closing important gaps. Review what is licensed, what is deployed, and who administers it. A single user subscription should not become a shared identity for an entire workforce; the right arrangement depends on the product and its licensing terms. Check whether Windows editions support the management and security features your design requires. Likewise, Microsoft 365 Commercial, GCC, and GCC High choices should follow data, contractual, and operational requirements. Rebnetik helps identify dependencies before migration or procurement, rather than treating a particular product name as proof of compliance.

A practical starting point

From uncertain scope to assigned action.

Establish the starting point
Review contract needs, information flows, asset ownership, current controls, and the responsibilities already assigned to your staff or providers. Identify uncertainties that need a business decision before a technical change.
Agree the remediation plan
Set priorities, deliverables, dependencies, and owners. Separate readiness work, ongoing operations, licensing, and any independent assessment costs so you can understand what the proposed scope covers.
Operate and retain evidence
Put agreed changes into practice, document procedures, and retain useful evidence of how controls operate. Review access and configuration as staff, projects, and contract requirements change.

Relevant project experience

Hands-on work behind the advice.

Rebnetik’s published projects include Windows endpoint security controls with Microsoft Intune and critical application support for a federal contractor, including software upgrades, patching, DNS configuration, and automated SSL certificate renewals.

Readiness has a defined role.

Readiness support helps you prepare controls, documentation, and evidence. It does not confer CMMC certification or replace the assessment required by your contract.

Before you choose support

Questions worth asking.

Do we need our whole business in the CMMC assessment boundary?

Not necessarily. The boundary depends on your information, systems, services, and applicable requirements. Begin with data flows and an accurate inventory. A smaller boundary requires a sound design and sustained separation, not simply moving a folder into a new tenant.

What evidence should we have before an assessment?

Expect to demonstrate how applicable controls operate through documentation, configurations, records, and staff knowledge. An SSP and remediation plan support readiness, but documents alone do not establish implementation. Evidence needs to match the environment and assessment requirements.

Who owns the work if we already have an IT administrator?

Agree a responsibility matrix before work begins. Your staff may own daily user support while Rebnetik handles defined remediation or management activities. Assign approvals, evidence retention, vendor coordination, and escalation explicitly so important tasks do not fall between providers.

What determines the project cost?

Scope, user and device counts, existing maturity, information boundaries, migration needs, documentation gaps, and ongoing operating requirements all matter. Request a scoped quote with assumptions and exclusions. Licensing and independent assessor fees should be distinguished from implementation and support.

Does readiness support provide CMMC certification?

No. Readiness services help you prepare and address gaps. Any required independent CMMC assessment must follow the applicable program requirements and be performed by an appropriately authorized assessment organization. Keep preparation, assessment, and any certification decision clearly separated.

Start with your environment
