Where cryptography carries weight.
The business and regulatory stakes differ by sector. The way to change safely, with evidence that it held, doesn’t.
What depends on cryptography, sector by sector.
In payments it’s card authorization and customer login. In healthcare it’s patient records that must stay private for decades.
Financial services and payments
Where change gets hard
A certificate can be renewed on time while the key underneath stays weak, and a checklist can pass while a real weakness remains.
Usually starts with
An audit cycle, a new rule or a customer questionnaire.
What Arcrix™ helps you decide
Which payment and identity systems to fix first, and what will show the fix worked.
What depends on cryptography here
- Card payments and authorization
- Customer login and identity checks
- Public and private certificates
- Financial records that must stay private for years
What we don’t claimReviewing evidence for selected card-payment requirements is not the same as being certified compliant. Your assessor still decides.
Capital markets
Where change gets hard
Signed messages have to stay verifiable long after they’re sent, and changing how you sign touches every counterparty that checks the signature.
Usually starts with
A question about signatures trusted today, forged later.
What Arcrix™ helps you decide
Which trust relationships to move first, and which counterparties must be ready before you change.
What depends on cryptography here
- Trade and settlement messages
- The signing keys behind trusted messages
- Connections to clearing houses and counterparties
- Records that must stay verifiable for years
Healthcare and life sciences
Where change gets hard
Patient and research data must stay private for decades, often on clinical systems that are slow to change.
Usually starts with
A board question about data stolen today and decrypted later.
What Arcrix™ helps you decide
What to change while a maintenance window allows it, starting with what must stay private longest.
What depends on cryptography here
- Patient records
- Research data
- Clinical systems and connected devices
- Links to partners and insurers
What we don’t claimArcrix™ does not assess medical-device safety or approvals.
Government and critical infrastructure
Where change gets hard
These systems are built to last decades, longer than the cryptography protecting them was expected to stay safe, and some equipment can’t be changed quickly.
Usually starts with
A policy deadline, with no clear picture of which systems can move in time.
What Arcrix™ helps you decide
How to sequence the move against a policy deadline, with the longest lead times first.
What depends on cryptography here
- Public services and long-lived records
- Identity and signing infrastructure
- Trust anchors that equipment relies on
- Links between agencies and operators
What we don’t claimArcrix™ holds no government or sovereign certification, and is not a complete assessment against any government framework.
Telecommunications
Where change gets hard
Network infrastructure is costly to change, so every change has to fit a planned maintenance window.
Usually starts with
An algorithm change or a hardware refresh.
What Arcrix™ helps you decide
What can change in a planned maintenance window, and which team owns it.
What depends on cryptography here
- Subscriber identity
- Network authentication
- Certificates and keys across network and IT
- Infrastructure that is expensive to touch
Technology and SaaS
Where change gets hard
Certificates and keys spread across services and pipelines, and no single team owns the whole picture.
Usually starts with
A certificate outage or a new CISO.
What Arcrix™ helps you decide
Which platform team acts, and on what.
What depends on cryptography here
- Service identities
- Certificates across services and environments
- Code signing
- Build pipelines
Rules, checked one control at a time.
Each rule gets its own answer from your evidence: met, not met, not enough evidence, or doesn’t apply.
- Requirement
- Applies
- Evidence
- Outcome
- Action
- Reassessed
How Arcrix™ treats rules
- A broken rule can need action even when the risk is low, and passing a rule never hides a real weakness.
- Arcrix™ checks the cryptography inside a standard, not the whole framework. It isn’t a certification, and your assessor still decides.
- Policy packs built on NIST’s cryptography standards, plus the policies you set yourself.
Built to be forwarded.
Every decision about cryptography has to survive four questions, from four different desks.
- CISO
Can I defend this?
Move your cryptography forward without becoming the reason something broke.
- Usually starts with
- Can’t see where cryptography is used. A failed audit item or a certificate outage, often soon after a new CISO arrives.
- What you’ll be able to say
- “I finally have a map, with owners.”
- CIO and CTO
Will it disrupt operations?
Cryptographic change on a schedule your teams can absorb, with dependencies found before the change window.
- Usually starts with
- Can’t afford to stop. An algorithm change or a hardware refresh, or systems running close to capacity.
- What you’ll be able to say
- “We can change without breaking what depends on it.”
- Risk and audit
Is the evidence audit-ready?
Every change confirmed and traceable, so “we fixed it” comes with evidence.
- Usually starts with
- Answering to someone. An audit cycle, a new rule, a customer questionnaire.
- What you’ll be able to say
- “I can show the evidence.”
- CFO and board
Is it worth the money?
Steady, planned change now instead of an emergency migration later.
- Usually starts with
- Long-lived secrets. A board question about data stolen today and decrypted later.
- What you’ll be able to say
- “We protected what matters most first.”
