Who We Help Best
Growing companies running on AWS with no dedicated security team or posture management
Engineering teams facing security scrutiny during due diligence, enterprise procurement, or regulated market entry
Founders and CTOs who want a clear, honest picture of their AWS security posture and where the real gaps are
Growing companies that want a security partner who stays in the room, not a vendor who delivers a report and disappears
Not the right fit if...
You need a penetration test or active exploitation simulation
You need application-layer or code security management
You already have an internal security team managing posture
You need multi-cloud coverage beyond AWS

Our Methodology

How We Think About Your Security

Most tools bury you in noise, hundreds of findings with little signal about what actually matters. Most firms hand you a report and disappear.

Osias takes a different approach. We run a structured review of your AWS environment's security posture against 200+ security controls, including AWS Foundational Security Best Practices. We surface the mission-critical gaps that, when left open, allow an initial probe to escalate into broader environment access.

Every finding is scored by blast radius, exposure, and deduplication, prioritizing what can cause the most damage if left unaddressed, not routine hygiene issues. Then we help you understand what it means, what to do about it, and how to stay ahead of it as your environment grows.

The posture review is where we establish your baseline. Our ongoing partnership is where we help you scale confidently.

Threat Exposure Status
STABLE
Detection controls active. Logging complete. You would know if something happened.
ALERT
Partial detection coverage. Incident response would be impaired.
BLIND
Critical detection controls missing. An active incident could go undetected. Forensic investigation impossible.
Assessed across logging completeness, detection coverage, and incident response readiness.

Sample Report

Prioritized Findings. Clear Action Plan.

Your security posture baseline across six domains — the starting point for understanding your risk, closing your gaps, and building toward a more secure environment. Every finding is validated and ranked by what can cause real damage. You get clarity, not volume.

Company Acme Technologies
Verdict Fair
Threat Status Alert

Acme Technologies has a functional AWS environment with meaningful security controls in place, but two critical gaps are holding this posture back. An unprotected root account and incomplete CloudTrail coverage are not routine hygiene issues. They are the two findings that, if exploited, allow an attacker to operate undetected with full account-level access. That combination is what drives the Alert threat status, not the volume of findings.

This environment has partial detection coverage and active misconfigurations across IAM and Network Security that require remediation before this posture can be considered acceptable.

Immediate remediation of the three Critical findings is required. Seven High findings across Network Security, Encryption, and Backup should follow within 30 days. None of these require architectural changes. They are configuration remediations an engineering team can execute in a single sprint.

About Osias

Intentional Posture Security. Built for Growing Companies.

Osias was founded to bring the thoughtfulness of enterprise security to growing companies. Our goal is to give every company the foundational security baseline they need to scale with confidence.

We review cloud environments, surface risk, and deliver clear controls to strengthen your security posture. We are not a tool you license or a firm you call once. We are the security partner that stays in the room as your environment grows.

Every engagement is led by a senior AWS practitioner with nearly a decade of hands-on experience building and securing cloud environments in financial services and healthcare. We approach each engagement with the same rigor and ownership used in real-world enterprise environments.

Our Approach
01
Outcomes over hours
We don't sell time. Every engagement is fixed scope, fixed price, and built around a defined outcome — not our time.
02
Posture first, not checkbox compliance
We assess what actually creates risk in your environment, not just what satisfies a framework.
03
Your partner.
Standing in the room with you, establishing a baseline you feel confident about.
Fixed Scope. Fixed Price.

Simple, Fixed Pricing

Fixed scope. Fixed price. No hourly rates.

Every engagement starts with a full AWS security posture review, your baseline across six security domains, a prioritized action plan, and a 30-minute walkthrough with your team. Pricing is based on the number of AWS accounts in scope. The review is where we establish the baseline. Remediation guidance and ongoing advisory are available from there.

FAQs

Common questions about how Osias works and what to expect.

Flat fee based on the number of AWS accounts in scope. No hourly billing. You know exactly what you are paying and exactly what you are getting before you sign. We don't sell time, we deliver a defined outcome. Ongoing advisory and retainer engagements are available as a next step following your initial review.
Yes. Many clients engage Osias on an ongoing basis for posture advisory and risk guidance after the initial review — helping them stay ahead of drift, interpret new findings, and build toward longer-term security maturity. If that is relevant to your situation, we can discuss it on the discovery call.
We use a read-only IAM role created via a CloudFormation template we provide. It takes under 10 minutes to deploy. We cannot write, modify, or delete anything in your environment. The role is scoped exclusively to our AWS account and uses a unique External ID specific to your engagement.
The automated scan takes 15–20 minutes. Our team reviews the results, filters noise, and produces your report. You receive the Executive Report within 48–72 hours of your deposit. The review call follows — and the advisory relationship continues from there.
Our Multi-Account ($6,500) and Extended ($9,500) tiers cover 2–5 and 6–10 accounts respectively. If you have more than 10 accounts, contact us and we'll put together a custom quote.
The Engineer Annex is a separate document containing resource-level findings — the specific AWS resources affected, risk context, and remediation guidance for each finding. It's designed for your engineering team to use as a working document during remediation. It's included in all tiers and released upon final payment.
No. This is a security posture review, not a compliance audit or certification. We review your AWS infrastructure posture across six core domains and give you a clear picture of your risks and priorities. We do not issue compliance certifications or attest to regulatory requirements. SOC 2 preparation is available as a separate engagement once your posture baseline is established.
Every engagement is led by a senior AWS practitioner with nearly a decade of hands-on experience building and securing cloud environments inside major financial services and healthcare enterprises. You are not getting a junior analyst or an automated tool — you are getting practitioner-level judgement applied to your specific environment.
Your AWS credentials are deleted immediately upon delivery of your Executive Report. Scan data including findings and analysis outputs are purged from our systems within 30 days of report delivery. We do not share, sell, or transfer your data to any third party.
