Which is the Best Email Security?

Your team is already using AI. The only question is whether you can see it, control it, and prove it.
Our AI infrastructure consulting closes that gap. MDL helps Kansas City companies build the secure foundation underneath AI, covering security, access, governance, licensing, approved tools, and Microsoft 365 integration, so you can move fast without handing your data to something you cannot audit. We have been securing systems for Kansas City businesses since 2003, and the same discipline applies here.
Whether you call it infra AI, infrastructure for AI, or just getting your tenant ready, the work is the same. Fix what AI can reach before you let it reach.
Most companies do not have an AI problem. They have an access problem that AI just made visible.
Copilot grants nobody new access. It only surfaces what that user could already open, which sounds reassuring and is exactly the problem. Overshared files used to be protected by friction. A salary spreadsheet shared to “Everyone except external users” in 2021 is now a one-line prompt.
That is why so many IT leaders end up delaying their Copilot rollout by a quarter or more over oversharing.
We work through six layers. You can start anywhere, but they stack in this order for a reason.
Identity first. Conditional access, MFA enforcement, device compliance, and what happens when an AI agent, not a person, is the thing requesting access. Microsoft now issues an Entra Agent ID for every new Copilot Studio agent, so agents get identities you can govern instead of service accounts nobody owns. Our managed AI services page covers the agent register and the migration problem with older agents.
The unglamorous work that decides everything else. We enumerate company-wide sharing links, hunt down “Everyone except external users” inside nested groups, retire project sites that outlived their projects, and archive ownerless content. If you hold even one Microsoft 365 Copilot license, SharePoint Advanced Management and its Data Access Governance reports are already paid for. Most clients have never opened them. Most clients have never opened them. The audit, correction, and recurring review work runs through our AI data readiness and security governance service.
A small sensitivity label taxonomy your salespeople can actually apply correctly, auto-labeling for the backlog, and Purview DLP wired to those labels. Worth knowing: the Microsoft 365 Copilot policy location in Purview DLP genuinely blocks content from being processed into answers. Most other Purview tools only detect after the fact.
Licensing decisions now change what you are able to control, not just what you can access. Microsoft 365 E7, the Frontier Suite, went generally available on May 1, 2026, and bundles E5 plus Copilot plus the Entra Suite plus Agent 365. We model what you actually need against what you already own, because plenty of companies buy a tier for a feature that came with their existing plan. Current per-seat figures are on our Microsoft 365 Copilot consulting page.
Banning ChatGPT does not work. It moves the behavior to personal phones where you have zero logging, and the employee still knows the tool made their email better. We build a short approved list, wire up a sanctioned alternative people will actually use, and put tenant restrictions in place so personal logins fail on corporate networks.
Copilot prompts and responses land in the user’s mailbox, which means eDiscovery, retention policies, and legal hold apply to them exactly like email. Audit Standard keeps those events for 180 days; Premium keeps them for a year. We already run managed Microsoft 365 services for companies across the metro, so we make sure that trail exists before you need it, not after.
Restricted SharePoint Search is being switched off. If you enabled it as a stopgap, Microsoft blocked new enablement on July 31, 2026, and retires the feature entirely on January 31, 2027, with the PowerShell cmdlets following on February 28, 2027. Microsoft has said plainly it will not migrate your configuration to Restricted Content Discovery for you. Do nothing and your restricted content simply becomes discoverable again.
CMMC Phase 2 was suspended, and that is not the relief it sounds like. On July 13, 2026, the Department of War suspended the third-party C3PAO certification requirement that was due to start November 10, 2026. Phase 1 self-assessments, DFARS 252.204-7012, and all 110 NIST SP 800-171 Rev 2 controls remain fully in force. With no assessor in the loop, the signature on that annual affirmation is yours, and False Claims Act exposure did not go anywhere. If your engineers are pasting technical data into a chatbot, that is a documented finding waiting to happen.
Missouri’s Insurance Data Security Act took effect January 1, 2026. Missouri still has no dedicated AI statute, but the state’s breach notification law requires notice within 45 days and carries penalties up to $150,000 per breach, enforced by the Attorney General. If you employ people in Illinois, HB 3773 already governs AI use in employment decisions. Multi-state employers headquartered here end up defaulting to the strictest rule in the stack.
We run Data Access Governance and Purview DSPM for AI against your tenant, the same way we approach any security risk assessment. This is the technical half of our broader AI readiness assessment and strategy engagement.
We do not clean up all of SharePoint. Nobody finishes that. We fix the sites where sensitive content meets broad access, expire stale sharing links, and archive dead sites so their permission debt retires in one move.
Three to five sensitivity labels, auto-labeling for the backlog, encryption on the top tier, and DLP keeping the second tier out of Copilot entirely. Then we test those policies against seeded content instead of assuming they work.
Roughly 2% to 5% of your seats, spread across departments and including finance or HR. A pilot built from IT volunteers proves nothing, because IT already knows what is overshared. Everyone gets an acceptable use policy and twenty minutes of training first.
Expansion is earned when oversharing findings trend toward zero, and DLP is verified against labeled content. We rerun Data Access Governance before every wave, because sharing debt regrows about as fast as people share.
It is the work of preparing your identity, data access, governance, and licensing so AI tools can run safely on company information. For most Kansas City businesses, it means auditing Microsoft 365 permissions and setting policy before turning anything on. It is closer to security work than to software development.
It is the security, access, licensing, and governance layer between your people and the AI platforms they use. We break the term down in full on what is AI infrastructure.
Scoped readiness assessments in this market commonly run in the low five figures, while full implementation depends on user count, tenant size, and compliance requirements. MDL prices are based on a review of your actual environment rather than a generic package. Request a proposal, and you will get a real number.
Not necessarily. A single Copilot license already unlocks SharePoint Advanced Management, which covers a lot of the permissions work. We check what your current plan includes before recommending a step up.
It depends almost entirely on how much permission debt your tenant is carrying and whether site ownership is still clear. A well-maintained tenant moves quickly, while one that has not had a permissions review in years takes considerably longer. We give you a timeline after the assessment, once we can see what we are actually working with.
Copilot can be configured to meet HIPAA expectations, but not out of the box. You need sensitivity labels, DLP policies scoped to the Copilot location, and audit retention in place first. That configuration work is exactly what this service covers.
The third-party certification requirement is paused, not cancelled. Phase 1 self-assessments, DFARS 252.204-7012, and NIST SP 800-171 obligations all remain in force, and your affirmation still carries legal weight. Contractors should keep remediating rather than treating this as a reprieve.
Blanket bans reliably backfire, because the work moves to personal phones where you have no visibility at all. The approach that holds is governed enablement, meaning an approved tool people actually want plus guardrails on what can leave. We help you pick and configure that alternative.
Missouri has no standalone AI statute as of 2026, but breach notification, consumer protection, and employment law all apply to AI systems. The Missouri Insurance Data Security Act took effect January 1, 2026, for insurers. Neighboring state rules can also apply if you employ people across the line.
MDL is based in North Kansas City and works across the greater metro, including Overland Park, Olathe, Lee’s Summit, Independence, Leawood, and Shawnee. We handle most of this work remotely and come on site when it helps.
You do not need an AI strategy deck. You need to know which sites are overshared, which tools your people are already using, and what to fix first.
Since 2003, Kansas City companies have trusted MDL to keep their systems secure, and that same team now delivers the AI infrastructure consulting that makes safe, scalable AI adoption possible.
