Most Microsoft 365 sharing risk comes down to two decisions: where shared content lives, and how external parties get access. We recommend SharePoint sites and authenticated guest accounts, and explain the reasoning here.

On July 13, 2026, the Department of War suspended CMMC Phase 2 and launched a 60-day review. What actually changed for OSCs — and why DFARS, flow-downs, and existing certifications still stand.

CMMC compliance cost depends on scope, level, and how much remediation you need. An honest breakdown of the cost categories and the decisions that move the number.

GCC or GCC High? The answer follows from your data and your contracts — ITAR, CUI Specified, and prime flow-downs. Here's how to make the call before you buy licenses.

A step-by-step CMMC Level 2 checklist for defense contractors — from scoping CUI and writing the SSP to gathering evidence and preparing for the C3PAO assessment.

POA&Ms buy limited time under CMMC 2.0 — only for certain lower-weight controls, only above a minimum score, and only for 180 days. Here's how the rules work.

Your SSP is the anchor document of a CMMC Level 2 assessment. Here's what belongs in it, the mistakes that sink assessments, and how to keep it assessment-ready.

A plain-English guide to Controlled Unclassified Information: definition, CUI vs FCI, categories, marking, handling, and what CMMC Level 2 requires of defense contractors.

Not all vCISO services are equal. These 10 questions expose the difference between a real security leader and a rebadged consultant before you sign.

The first 90 days of a vCISO engagement, mapped out: risk assessment, roadmap, policy work, and the leadership reporting that proves the program is working.

A candid look at vCISO vs. full-time CISO: cost, availability, breadth of expertise, and the situations where each model is the right call.

Annual pen testing is the floor, not the rule. See how PCI DSS, CMMC, SOC 2, HIPAA, and FedRAMP each define testing frequency — and when to test more often.

Virtual CISO pricing explained: engagement models, market rate ranges, what drives cost up or down, and the deliverables you should expect at every tier.

What a pen test really costs: market price ranges, the factors that drive them, red flags in cheap tests, and how to scope your engagement so you pay for depth, not paperwork.

RPS Defense earned a perfect 110 of 110 on its CMMC Level 2 assessment with A-LIGN, an authorized C3PAO, with zero open findings (no POA&M) — on the M365 GCC High enclave and security program designed, implemented, and managed by Essendis.

Achieving CMMC certification is a milestone, not a destination. The contractors who thrive in the post-Phase 2 environment are treating cybersecurity as an operational capability—not just an audit event.

CMMC Phase 2 lands November 10, 2026. For defense contractors still treating compliance as an afterthought, the budget impact will be sudden and steep. Here's how to plan ahead.

CMMC Level 2 is currently locked to NIST SP 800-171 Revision 2, but Revision 3 is on the horizon. Here's what's changing, what you can implement now, and how to avoid being caught off guard.

CMMC compliance doesn't stop at the prime contractor. Flow-down requirements are reshaping how the entire defense supply chain handles CUI—and primes face False Claims Act exposure if their subs fall short.

With only ~103 authorized C3PAOs serving an estimated 80,000 organizations that need Level 2 certification, the clock is ticking. Here's what the shortage means for your timeline and what you can do about it.

Per the 2025 State of SMB Cybersecurity study, 57% of SMBs call cybersecurity their top priority, yet only 51% have the policies in place to sustain it.

CMMC is enforceable as of November 10, 2025: most contractors self-assess, but those handling ITAR data or sensitive CUI may need third-party assessment.

With 48 CFR past regulatory review, CMMC requirements enter all defense contracts from November 10, 2025, and primes and subcontractors alike must comply.

CMMC Level 2 requires a C3PAO assessment, but with fewer than 600 qualified assessors for hundreds of thousands of organizations, bottlenecks loom.

Federal agencies beyond the DoD are starting to treat certain data as CUI, signaling that CMMC-style compliance may soon extend past defense contracts.

CMMC compliance costs weigh on SMBs and lower-tier subcontractors; some may exit DoD contracting, with ripple effects across the defense industrial base.

CMMC requirements extend beyond primes and subcontractors to third-party providers in their ecosystem, even those not directly tied to defense contracts.

CMMC Level 2 brings over six times more security requirements than Level 1 and a third-party assessment based on NIST SP 800-171 to safeguard CUI.
