Both are excellent password managers, and if this were a normal buying decision I'd tell you to pick either. It isn't. Keeper holds a FedRAMP authorization; 1Password doesn't. For a contractor whose vault sits inside a CUI boundary, that's the whole comparison. But there's a catch that costs people real money: the authorization is on Keeper Security Government Cloud — a separate SKU from the commercial Keeper Business plan you'd land on by default. Buy the wrong edition and you have the logo without the authorization.
This is one of those decisions where the popular answer and the correct answer diverge, and the gap only shows up under assessment. Ask a security forum which password manager to use and 1Password wins on polish, on family plans, on the interface people actually enjoy. Ask which one survives a CMMC conversation and the answer changes — not because 1Password is weak, but because it isn't playing the game your contract signed you up for.
What follows is the honest version: what each one actually holds, the SKU trap that undoes the whole exercise, where 1Password genuinely still wins, and what to write in your SSP so the tool you bought counts for something.
A password manager isn't a control. But it's one of the highest-leverage ways to satisfy several, which is why it shows up early in a sensible CMMC build.
The Identification & Authentication (IA) family cares about people being uniquely identified, authenticators being managed properly, passwords not being reused or trivially guessable, and credentials being protected from disclosure. A managed vault does that work directly. It also does something subtler and more valuable: it produces the evidence. Provisioning records, access logs, who-had-what-when. Without a platform, your answer to "how do you manage authenticators?" is a story. With one, it's a report.
Access Control (AC) benefits too. When someone leaves, deprovisioning is one action inside the console instead of a scavenger hunt across fourteen systems hoping nobody wrote the password on a sticky note. That's the difference between a control that operates and a control you assert.
Here's the comparison, stated as fact rather than vibe. Both of these are verifiable, and you should verify them rather than take my word — that's the whole point of this site.
| Keeper Security Government Cloud | 1Password | |
|---|---|---|
| FedRAMP | Authorized — High baseline | None — not listed |
| Marketplace package | FR2116544598A | — |
| FIPS 140-3 validated module | Yes | No claim |
| Other posture | Previously Moderate, upgraded to High | SOC 2 Type 2 |
| Defensible for a CUI-scoped vault | Yes | Not on a FedRAMP basis |
Two things worth saying about that table so it isn't misread.
1Password isn't overclaiming. They don't advertise a FedRAMP authorization, because they don't have one. SOC 2 Type 2 is a real, rigorous certification and it means something — it's just answering a different question than the one the DoD is asking. There's no dishonesty here to catch them out on. It's a product built for a market that isn't yours.
The Marketplace has changed its vocabulary. If you go look Keeper up, you may see the status rendered as "FedRAMP Certified" and the baseline as "Class D" rather than the Authorized/High language your contracts and your primes still use. That's the Marketplace's newer terminology, not a different authorization. Translate it when you write your SSP — your assessor and your prime still speak the old dialect, and matching their vocabulary avoids a pointless round of questions.
Password and privileged access management with a FedRAMP authorization at the High baseline and a FIPS 140-3 validated module underneath it. For a contractor whose vault sits in or near the CUI boundary, this is the shortest path from "we use a password manager" to "here's the authorization, here's the access record, next question." Buy the Government Cloud edition specifically — see the next section, because this is exactly where people lose the benefit they paid for.
This is the part I actually wrote this article for, because it's the mistake I see most and it's invisible until it isn't.
Read the authorized product's full name: Keeper Security Government Cloud Password Manager and Privileged Access Manager. Not "Keeper." Not "Keeper Business." The authorization attaches to a specific government offering. Go to the website, click the obvious button, sign up for the business plan, and you have bought a genuinely good commercial password manager that does not carry the authorization you chose it for.
How to not get caught: before you buy anything for a CUI-scoped system, look up the product on the FedRAMP Marketplace and read the product name on the listing character by character. Then make sure the thing in your cart matches that string exactly. If the listing says "Government Cloud" and your invoice says "Business," you have a finding waiting to happen — and worse, you'll have documented it yourself in your SSP.
I'm not going to pretend this is a blowout, because it isn't, and a comparison that trashes the loser is a comparison you shouldn't trust.
The honest summary: 1Password loses this comparison on exactly one axis. That axis just happens to be the one your contract cares about — if, and only if, your vault is in scope.
Notice that the first two steps have nothing to do with either product. That's deliberate — this is a scoping decision wearing a shopping decision's clothes.
Whichever you pick, the words matter more than the logo — an assessor reads your SSP, not your invoice.
Name the exact edition. Write "Keeper Security Government Cloud," not "Keeper." The two have different authorizations, and an assessor who checks will find the difference. Getting this wrong in writing is worse than not mentioning it, because now the overclaim is yours rather than a misunderstanding.
Map it to the controls it genuinely supports and stop there. A vault helps with authenticator management and access control. It does not make you compliant, it does not encrypt your CUI at rest, and it does not do anything about the other hundred-odd controls. Overreach in an SSP is the fastest way to turn a routine review into an adversarial one.
Say who administers it, and how accounts are provisioned and deprovisioned — with the record to prove it. The tool is half. The named owner and the operating procedure are what make it a control instead of a purchase.
Want to see where identity and authentication sit against the other control families before you spend? The free SPRS score estimator gives you a baseline in about two minutes — so you buy the stack you need rather than the one a vendor's landing page suggests.
Buying the right SKU is the easy half. The half that passes is the paperwork: an Identification & Authentication policy, a System Security Plan naming the exact product and who administers it, the 20 required policies, and a per-control SPRS scorer. The CMMC Level 2 DIY Compliance Kit is all of it, editable, built for a small shop doing this itself.
No. As of this writing 1Password doesn't appear on the FedRAMP Marketplace in any status, and the company doesn't claim a FedRAMP authorization. Its published security posture centers on SOC 2 Type 2 — a genuine, rigorous certification that simply isn't the one the DoD asks about when a cloud service touches CUI. Verify current status yourself on the Marketplace before relying on any vendor claim, including this one.
Yes — but read the product name carefully. The authorization belongs to Keeper Security Government Cloud Password Manager and Privileged Access Manager, package FR2116544598A, listed at the High baseline (the Marketplace currently labels this "Class D" under its updated terminology). It was previously authorized at Moderate and upgraded. Commercial Keeper Business is a different SKU and is not the authorized instance. Sign up for the standard business plan expecting the FedRAMP posture and you didn't buy what you think you bought.
It isn't a control itself, but it's one of the most efficient ways to satisfy several. The Identification & Authentication family is concerned with unique identification, authenticator management, password complexity and reuse, and protecting authenticators from disclosure. A managed vault does that work and — critically — produces the access records and provisioning trail that let you evidence it. Access Control benefits too, since deprovisioning a departing employee becomes one action instead of a scavenger hunt.
Because your vault is a cloud service holding the keys to everything else, including the systems where CUI lives. DFARS 252.204-7012 requires cloud services that store, process, or transmit covered defense information to meet requirements equivalent to the FedRAMP Moderate baseline. Whether your specific vault falls inside that scope depends on how you've scoped your environment — a decision you have to make and document. What isn't ambiguous: a service holding credentials to CUI systems will draw an assessor's attention, and an authorization already in hand is a much shorter conversation than arguing equivalency.
If you handle CUI and your vault is in scope, the FedRAMP authorization is a real advantage and Keeper Government Cloud is the defensible pick. If you're Level 1 with FCI only, or your vault genuinely sits outside your CUI boundary, 1Password remains excellent and there's no compliance reason to move. Don't switch because a comparison article told you to. Switch because you scoped your environment, found your vault inside the boundary, and needed an authorization you didn't have.
Name the exact product and edition — not just the brand. Write "Keeper Security Government Cloud" rather than "Keeper," because the two have different authorizations and an assessor who checks will find the difference. State which controls the tool supports, who administers it, how accounts are provisioned and deprovisioned, and where the access records live. Map the tool to the controls it genuinely supports and no further. A vault doesn't make you compliant, and an SSP that implies it does is the kind of overclaim that turns a routine review into a hard one.
