Microsoft 365 and Azure Security Assessment

Everything moved to Microsoft 365. The security review never did.

Your conditional access policies were set up during migration. Microsoft has changed its security defaults hundreds of times since. Rivial checks about 500 security settings across your tenant with read-only access you own, and hands you two things: an executive summary with your number and the gaps that matter most, and a full risk-rated workbook that names every account and resource that failed, ranked, with a fix for each.

Set once. Never reviewed.

Most organizations moved to Microsoft 365 five, six, or seven years ago. A vendor set up the conditional access policies during migration, everyone moved on, and those policies have not been touched since. Meanwhile Microsoft changes security defaults, retires old settings, and ships new recommendations every month. Reading those updates is easy. Implementing them is a full-time job no one on your team has. So the gap between how your tenant is configured and how it should be configured grows quietly, year after year, while more of the organization moves into it: email, files, identity, and now AI.

Drift

Drift

Policies set in 2019 are running against a Microsoft tenant that looks nothing like 2019. Nobody owns keeping them current.

Concentration

Concentration

Email, files, identity, and soon Copilot all live in one tenant. One compromised environment is the whole organization, not one system.

Nobody knows the number

Nobody knows the number

Most IT leads cannot state their Secure Score without looking it up, and a good score can sit on top of real gaps the score never checks.

Examiners are asking

Examiners are asking

FDIC and NCUA attention is shifting to cloud and AI use. "Our vendor set that up" is not an answer that holds up in an exam.

One tenant. Total blast radius.

When a Microsoft 365 tenant is compromised, the attacker does not need to bring anything in. The tools are already there. Remote wipe, mail forwarding, admin role assignment, and access to every file the organization has moved into SharePoint are built-in features, and in a tenant nobody has hardened they work for whoever holds the credentials.

That is what concentration risk looks like now. Trusting Microsoft with everything was probably the right call. Trusting Microsoft is not the same as configuring Microsoft. The configurations are yours, the drift is yours, and when the examiner or the attacker shows up, "our vendor set that up in 2019" belongs to you too.

Why this matters now

A strong Secure Score is not the same as a secure tenant.

Most IT leaders cannot state their Secure Score without looking it up, and when they do, the number does not say much. Microsoft itself says Secure Score is not a risk measure: it weights improvement actions, not threats, and it only counts the settings Microsoft chose to score.

An organization can hold a strong score and still have shared mailboxes that accept direct sign-in, standing Global Administrator roles on everyday accounts, and backups that one admin action can erase.

Rivial checks about 500 controls across identity, email, collaboration, compute, storage, and databases, well beyond what the score covers, and rates each gap by the threat it exposes you to. Guessing is not a posture.

Unnamed findings

Unnamed findings

A percentage does not tell you which 400 accounts are missing MFA or which 17 storage accounts have soft delete turned off.
No priority

No priority

A dashboard scores a setting on one test server the same as a setting on every production system.
Vendor blind spots

Vendor blind spots

If a managed service provider or a migration partner set up the tenant, you need an independent view of what they actually configured.
Copilot readiness

Copilot readiness

Copilot can only be as safe as the tenant underneath it. Over-shared SharePoint sites and stale permissions were tolerable when a person had to go find the data. An AI assistant that indexes everything removes that friction.
Cloud Configuration Security Assessment

Benchmark your whole tenant. Get a roadmap, not a scan.

An advisory assessment of your Microsoft 365 tenant and Azure subscriptions against the Rivial Cloud Configuration Standard, about 500 security controls covering identity, email, collaboration, compute, storage, and databases. Rivial collects the settings with read-only access, an analyst validates every finding against the evidence, and you receive a ranked list of what to fix with step-by-step instructions for each item. Most engagements run three to six weeks from kickoff to final report, with about five to ten hours of your team's time.

What's included:

Scoping

We confirm your Microsoft 365 license, which Azure subscriptions are in scope, and your maturity target: Baseline, the settings every organization should meet, or Enhanced, which adds defense-in-depth controls on top.

Read-only access setup

Your team creates a single-tenant app registration you own and a guest reader account, following our access guide. No write role is requested. You can revoke it the day the report lands.

Automated collection

Rivial collects the configuration of about 500 security controls across Microsoft 365 and Azure. Services you do not use are recorded as not applicable, so the score reflects your environment.

Analyst review

Every finding is validated by a Rivial analyst against the collected evidence before it reaches your report. Findings, not recommendations. Nothing is reported as Critical until it has been confirmed.

Evidence request

For the few settings read-only access cannot see, you receive a short request listing the minimum role, the exact steps, and the file to return. Screenshots or a screen share both work.

Readout

A one-hour meeting with your IT leadership to walk the executive summary and the top of the fix list, with an optional management response to add business context to any finding.

What You Walk Away With

Your number, your gaps, and your roadmap.

The promise is clarity. You learn exactly how far off the mark you are and what it will take to get where you need to be. Two readers get two different documents: the leader who approves the work gets a few pages, and the admin or MSP who does the work gets a full risk-rated workbook with every step.
  • Executive Summary. A few pages for leadership: overall posture, compliance score against your chosen maturity target, the most significant gaps, what an attacker could do today, and what to do in the next 30 and 90 days.
  • Risk-Rated Remediation Workbook. An Excel workbook with one row per finding: priority, position in the fix order, every affected account or resource by name, a link to the portal page where the change is made, numbered fix steps, and how to confirm. Owner, target date, and status columns are yours to fill in.
  • Management Response. Inside the workbook. For the handful of settings that depend on business context, your team records a decision: fix it, with an owner and date, or accept the risk and record why.
  • Risk Rating Methodology. On request, how every priority is derived, the threat scenario behind each control, and the sources behind each rating. It goes to anyone who asks, including your examiner.
How it works

Minimal lift. Full picture.

Three phases. Your team's total time is about five to ten hours. The calendar is set mostly by how quickly access is granted, not by our hours.

number-01
Scope and connect
(Weeks 1 to 2)

We confirm license, subscriptions, and maturity target. Your admins create the read-only app registration and guest reader account from our guide, usually one to three hours of their time.

number-01
Collect and review
(Weeks 2 to 4)

Rivial runs the collection, rates every control, and an analyst validates each finding against the evidence. You receive a short evidence request for the few settings read-only access cannot see.

number-01
Report and readout
(Weeks 4 to 6)

You receive the executive summary and the risk-rated remediation workbook, walk the priorities with us in a one-hour readout, and record management responses on the findings that need your context.

How A Finding Gets Its Priority

Ratings that hold up in front of the board and the examiner.

Every control in the standard is tied to a documented threat scenario, rated for likelihood and impact on NIST SP 800-30 scales, with a written and sourced basis. Your environment's evidence can raise a rating. Nothing lowers one. The same inputs produce the same order every time, so nothing on the list is a matter of opinion on the day.
Bind

Bind

  • Each control maps to an adversary scenario: account takeover without a second factor, abuse of privileged roles, destruction of data and its backups, and others.
Combine

Combine

  • Likelihood and impact meet on the NIST SP 800-30 matrix to set the control's inherent risk.
  • Inherent risk is fixed, so next year's results compare to this year's.
Adjust

Adjust

  • If most of the resources checked fail, likelihood goes up.
  • If the failed resources hold identities, secrets, or role assignments, impact goes up.
Order

Order

  • Every finding gets a priority (Critical, High, Medium, or Low) and a position from 1 to n in the fix list.
  • Critical means before the next change window.
