Organizations searching for Vanta alternatives often need more than software automation. While platforms like Vanta provide valuable monitoring and evidence collection, they cannot perform the formal examinations and assessments required for compliance. That’s why many security leaders choose to work directly with a firm, like Securisea, that holds those credentials. 

This comparison examines Vanta and its alternatives, why organizations should work with a multi-credential assessment partner instead, and how to evaluate both software and comprehensive service providers for SOC 2, PCI DSS, and GovRAMP requirements.

Vanta Alternatives at a Glance

What Vanta Does

Vanta is a compliance automation platform that connects to your cloud, identity, HR, and endpoint systems, continuously collects evidence against a catalog of frameworks, and gives you a shared workspace that an outside auditor can use during fieldwork. Vanta supports SOC 2, ISO 27001, PCI DSS, HIPAA, GDPR, NIST CSF, CMMC, and others, and in 2025 added AI-agent features and an autonomous penetration testing option delivered by a partner.

What These Platforms Are Not Built To Do

Each of these platforms is honest about what it is: software. None of them is a licensed CPA firm, none is a PCI Qualified Security Assessor company, none is a FedRAMP or GovRAMP 3PAO, and none performs penetration testing as a first-party service line. That matters because the documents your customers, regulators, and acquiring banks actually accept are signed by credentialed assessors, not by the software you used to prepare.

A few specific implications worth thinking through before you sign an annual contract with a platform:

Automation Is Not the Same As Assessor Judgment

The AICPA has published guidance on this directly, and the short version is that a service auditor cannot simply rely on the outputs of a compliance tool. The auditor has to evaluate the reliability of the data, test the controls themselves, and apply professional judgment. That human layer is where the risk actually gets reduced, and it is the work a platform is not designed to perform.

Platforms Tend Toward a Common Control Template

Standardized mappings are useful for getting started, but most mature security programs have controls that do not fit cleanly into a default library. Custom controls still need manual evidence and an assessor who understands how to test them, which is where many teams run into what practitioners sometimes call the automation gap.

Platform Readiness and Audit Readiness Are Related but Not Identical

A green dashboard tells you the automated checks are passing. It does not tell you whether your system description is defensible, whether your scope is drawn the way an auditor will accept, or whether your control design will hold up under testing. That gap is where engagements go sideways late in the calendar.

Why Work with a Multi-Credential Assessment Partner Instead

A different approach, and the one Securisea is built around, is to engage a single firm that holds the credentials required to actually perform the attest, assessment, and testing work your program depends on. Securisea operates as a licensed CPA firm that performs SOC 1, SOC 2, and SOC 3 examinations; a PCI Qualified Security Assessor company; a FedRAMP 3PAO; a GovRAMP 3PAO; and a penetration testing practice staffed by GPEN-certified testers. For teams balancing several of those obligations at once, the shape of the engagement changes in a few practical ways.

The strongest compliance assessment partners offer readiness support, formal assessment coordination, and ongoing compliance across SOC, PCI DSS, and GovRAMP.

One Accountable Firm for the Work That Ends Up on Paper

When the firm that guides you toward audit readiness is also the firm that can sign the SOC report, the PCI Report on Compliance, or the FedRAMP Security Assessment Report, there is one accountable party for the outcome. Handoffs between a platform vendor, a separate CPA firm, a separate QSA, a separate 3PAO, and a separate pen test vendor are where scope drifts, evidence expectations diverge, and timelines slip. Consolidating those handoffs reduces a real source of program risk.

A Control Environment Scoped by Experts Who Will Actually Test It

SOC 2, PCI DSS, FedRAMP, and GovRAMP may look at overlapping territory, but each has its own scoping conventions and evidence expectations. When the same firm scopes the environment, advises on readiness, and later performs the assessment, your control set is shaped from day one by people who know what their own assessors will accept. That is a materially different starting point than aligning to a generic framework template and hoping it maps cleanly during fieldwork.

Penetration Testing Performed by the Firm, Not Brokered Out

Penetration testing sits at the center of several of these programs. PCI DSS v4 requires external and internal pen tests at least every twelve months and after significant changes, with segmentation testing every six months for service providers. FedRAMP requires a 3PAO-directed penetration test following the FedRAMP Penetration Test Guidance, including specific attack vectors and announced testing windows. 

Securisea performs this work in-house, with GPEN-certified testers and a 30-day retest window included in engagements. Findings flow directly into the same team that understands where they fit within your broader compliance posture, rather than being handed off as a separate deliverable.

A Note on Independence

When a single firm offers both readiness-style advisory and the attest or assessment it will later perform, independence is a real constraint, and a serious firm says so explicitly. Under the AICPA Code, a CPA firm can provide non-attest services to an attest client only when the client retains management responsibilities, designates a qualified individual to oversee the work, and the firm does not audit its own output. The governing rule in the FedRAMP and GovRAMP world is similar: an A2LA-accredited 3PAO must separate its advisory work from its formal assessment work, with documented safeguards.

Securisea addresses this the way reputable firms address it: by keeping its non-attest and attest work on separate teams with separate reporting lines, documenting the arrangement up front, and declining engagements where the separation cannot be maintained. This is the same structural approach used by the large CPA firms that perform both advisory and audit work, and it is the reason the two service lines can coexist under a single firm without compromising the integrity of the resulting report.

Moving Beyond Automation to Attestation with Securisea

If your program is primarily about standing up evidence collection quickly, a compliance automation platform may be a reasonable starting point, with the understanding that you will still need to engage an outside CPA firm, QSA, 3PAO, and pen test provider to actually complete the work. If your program spans SOC, PCI, FedRAMP, or GovRAMP, and you want one accountable firm with the credentials to perform the assessments your customers and regulators will accept, Securisea is a top Vanta alternative.

Software developers who build payment infrastructure often think of themselves as vendors. The moment cardholder data touches their systems in flight, though, they are service providers under PCI DSS. That single distinction reshapes their compliance obligations, their enterprise sales pipeline, and ultimately their revenue.

This case study on PCI validation for software developers draws on several real Securisea engagements, consolidated into a single composite client we will call PayStream Technologies. Identifying details have been changed, but the pattern — the trigger, the scoping surprises, the remediation effort, the business outcome — is one we see repeatedly at cloud-native payment software companies.

Meet Example Client: PayStream

PayStream Technologies is a 65-employee fintech that builds a cloud-based payment gateway API. Annually, it processes 2.3 million transactions for roughly 100 merchant clients. On paper, the engineering team was running a tight shop: modern CI/CD, a respectable vulnerability management program, and an SDLC that most startups would envy.

The problem: three enterprise deals worth $600K in annual recurring revenue stalled in procurement. In each case, the prospect’s security team asked for a current PCI DSS Attestation of Compliance (AOC) for Service Providers. PayStream did not have one. They had been self-attesting against a Self-Assessment Questionnaire (SAQ) and assuming that was sufficient. It was not. Any organization processing, storing, or transmitting cardholder data on behalf of others operates at Level 1 as a service provider and must be validated by a Qualified Security Assessor (QSA).

Choosing a QSA

PayStream interviewed three Qualified Security Assessor Companies and selected Securisea. The decision came down to four things:

• Deep experience with cloud-native payment gateways and API-based architectures
• A two-track assessor model: an advisory team to work alongside PayStream through scoping and remediation, and an independent QSA team to perform the formal validation, with documented separation between them
• Membership in the PCI Security Standards Council’s Global Executive Assessor Roundtable (GEAR), which is the SSC’s formal engagement channel with the most active QSA firms
• References from comparable SaaS companies that had been through the same wall PayStream was now hitting

That two-track model matters more than it sounds. A single firm that holds the QSA qualification and can field both advisory and independent assessor resources avoids the coordination overhead of splitting the engagement across two vendors, while still producing an attestation that will hold up to card-brand scrutiny.

The Path to PCI Validation for Software Developers

Based on PCI DSS compliance timelines for similar complexity environments, here's how PayStream's  compliance journey might go:

Note: The table and findings shown are for illustrative purposes. Actual assessment scope varies by transaction volume, merchant level, and cardholder data environment complexity. The underlying PCI DSS security requirements apply uniformly to all entities.

Phase 1: Scoping and Gap Analysis

Scoping is not a deliverable Securisea hands over. It is a joint exercise, and it is where most of the learning happens. Securisea’s advisory team worked with PayStream’s engineering, infrastructure, and compliance leads to map every system that stored, processed, or transmitted cardholder data, every system connected to those systems, and every system that could affect their security. This defined the cardholder data environment (CDE) and, just as important, what sat outside it.

Because PayStream operates as a service provider, the scoping exercise also produced a Responsibility Matrix, the document that makes explicit which PCI DSS controls PayStream owns, which the merchant owns, and which are shared. This is a service-provider-specific artifact that enterprise customers will demand during their own assessments, and getting it right early saves months of back-and-forth later.

The gap analysis surfaced findings that were realistic for a company of PayStream’s maturity. Among the most consequential:

• A backlog of known vulnerabilities in third-party software components, with no formal inventory process to track them
• No automated code review integrated into the path to production
• SDLC documentation that described the team’s actual practice only loosely, and did not meet PCI DSS expectations for a service provider
• Production access privileges for developer accounts that exceeded what job function required
• Logging in place, but without the centralized review and alerting PCI DSS requires

Phase 2: Remediation

Examples of the remediation work PayStream completed, with Securisea’s advisory team providing interpretation and readiness guidance throughout:

• New change-control procedures with documented impact assessment, testing, and approval gates before any production release
• Centralized logging with automated review and alerting on security-relevant events
• Migration to TLS 1.2+ (TLS 1.3 where supported) across all in-scope data flows, with cryptographic key management formalized
• Least-privilege access review across the CDE, with multi-factor authentication enforced on all access paths
• Vulnerability remediation SLAs by severity, with a documented risk-based approach for the remainder

Phase 3: Testing and Readiness

Before the formal assessment, PayStream completed the testing PCI DSS requires at evidence level: internal vulnerability scans, external ASV scans by an Approved Scanning Vendor, and independent penetration testing covering both the application and network layers. Securisea’s advisory team then ran a readiness walkthrough against the full control set, identified the last remaining soft spots, and gave PayStream time to close them before the independent assessors began their work.

Phase 4: Formal Assessment

Securisea’s independent QSA team — distinct from the advisers who had been on the ground — conducted the PCI DSS assessment of PayStream’s CDE. Assessment activities included examining policies and evidence, interviewing personnel across engineering and operations, observing controls in action, and performing hands-on testing. Two findings emerged during fieldwork; PayStream remediated them within days, and the assessors re-tested before finalizing the report.

The final deliverables were the Report on Compliance (ROC) and the Attestation of Compliance (AOC) for Service Providers, which PayStream submitted to its acquiring banks and to the card-brand service-provider registries.

After the QSA signs the ROC, the PCI SSC itself often runs a quality-assurance review that generates questions and occasionally requests clarifications from the assessor. Having a QSA firm that has been through this loop many times — and that will stand behind its workpapers during that review — is the difference between a clean listing and a months-long delay. Securisea shepherded PayStream through the council’s QA process without the attestation being held up.

Results and Business Impact

Within 30 days of receiving the AOC, all three stalled deals — the $600K in blocked ARR — closed. Average enterprise deal size rose meaningfully as PayStream moved into conversations with prospects who had previously screened them out at the RFP stage.

The remediation work produced operational gains beyond the AOC itself: a sharp drop in production security defects, meaningfully less manual QA effort as automated checks absorbed the load, and a faster, more confident path to production.

Ready to Begin Your Compliance and Validation Journey?

If your company builds software that touches cardholder data in flight, you likely are operating as a service provider, whether or not you have called yourself one, and you may have an enterprise pipeline that will eventually depend on producing a current AOC.

Securisea has walked dozens of payment software companies through exactly this path. As a GEAR member firm with a deep QSA bench and a disciplined separation between advisory and independent assessment personnel, we can meet you at scoping and stay with you through the SSC’s final QA review.

Most people searching "SOC 2 vs ISO 27001" assume they need to pick one. In reality, most organizations pursue multiple compliance frameworks, and per the AICPA, SOC 2 and ISO 27001 share roughly 80% control overlap. The expensive mistake isn't choosing the wrong one; it's treating them as separate projects instead of a sequenced roadmap. This guide helps you decide which to pursue first based on your buyers, geography, and growth stage, then shows how to make your first framework speed up the second. Hi

Defining SOC 2 & ISO 27001

SOC 2 is an attestation engagement developed by the AICPA that evaluates whether specific controls are operating effectively. ISO 27001, by contrast, is an international ISMS standard that certifies your entire management system for information security. The key difference is, one tests controls while the other certifies the system that governs them.

SOC 2 vs ISO 27001 Compared

How the First Framework Accelerates the Second

While different, both frameworks share roughly an 80% overlap in foundational security elements. This means that once you establish one of those elements, you can leverage it for both frameworks. Here are some practical examples:

• Policies and procedures: Information security policy, acceptable use, access control, incident response, and vendor management can all be written once and then mapped to both frameworks.
• Risk assessment: ISO 27001 requires a formal risk assessment, and SOC 2 auditors expect one. Instead of doing two risk assessments, you can do one and use it for both frameworks.
• Technical controls: Encryption, MFA, logging, monitoring, and vulnerability management can all be implemented once and used as evidence for both.
• Training and awareness: The same program can satisfy both frameworks.

Once you address the overlap, you can do incremental work to address the unique requirements of the different frameworks. For example, ISO 27001 adds ISMS governance requirements like management review, internal audit, and continual improvement that SOC 2 doesn’t require. It is also less flexible in scope than SOC 2, requiring a comprehensive ISMS covering your defined scope, while SOC 2 allows you to choose which Trust Services categories to include. 

The incremental effort will account for roughly 30-50% additional work, rather than a full restart.

How To Decide Which Framework to Sequence First

Start with SOC 2 if:

• Your buyers are primarily North American SaaS companies or enterprises
• You're being asked for a SOC 2 report in sales cycles right now
• You're a startup or early-growth company building your first formal security program

Start with ISO 27001 if:

• Your buyers are primarily outside North America or in regulated industries (finance, healthcare, government)
• You're selling into the EU, UK, or APAC markets where ISO 27001 is the default expectation
• Your organization already has mature security processes that need formal certification
• You want a management system foundation that will support multiple frameworks long-term

Start with both simultaneously if:

• You're selling globally and facing both requests in parallel
• You have the budget and team bandwidth for a combined implementation
• You're using a compliance automation platform that maps controls across both frameworks

Five Sequencing Mistakes To Avoid

Thanks to the overlap between the ISO 27001 and SOC 2, your biggest worry shouldn’t be choosing the wrong framework. Instead, you should look out for these five sequencing and implementation errors that could waste your time and resources.

1. Treating them as completely separate projects: Building siloed control sets instead of a unified control framework wastes the 80% overlap.
2. Starting ISO 27001 without a risk assessment and expecting to finish in six months: ISO 27001 requires a formal risk assessment before you can define your Statement of Applicability. Skipping this adds 2–4 months.
3. Scoping SOC 2 too narrowly to check a box: A SOC 2 report scoped to a single product may not satisfy enterprise buyers asking about your full environment. Rework means more time and energy spent than getting the scope right from the start.
4. Assuming SOC 2 is only for U.S. companies (or that ISO 27001 isn't needed in the U.S.): SOC 2 is used by organizations worldwide, and ISO 27001 is increasingly requested by U.S. enterprises, especially in regulated sectors.
5. Waiting until a customer asks before starting: Both frameworks take months. Starting reactively means losing deals during the implementation window.

Three Real-World Sequencing Scenarios

Scenario A: U.S. B2B SaaS Startup, 50 Employees, Series B

Buyers are North American enterprises that are requesting SOC 2 in security questionnaires. Start with SOC 2 Type II, then layer ISO 27001 within 12 months using the same control evidence and adding ISMS governance.

Scenario B: European Fintech Expanding Into the U.S.

ISO 27001 is already in place for EU clients. Add SOC 2 by mapping existing ISO controls to the Trust Services Criteria. The incremental effort will likely result in 30-40% additional work, mostly documentation reformatting and engaging a CPA firm.

Scenario C: Mid-Market Healthcare SaaS, 200 Employees, Selling Globally

Both frameworks are needed simultaneously. Use a unified control framework from day one. Engage a firm that can coordinate both assessments to reduce duplicated evidence collection.

Choose the Right Framework and Gain Your Competitive Edge

Instead of asking yourself what the difference is between SOC 2 vs ISO 27001, you should focus on deciding which you should engage with first based on your market, your current security posture, organizational maturity, and future goals. From there, you can build a compliance foundation that scales.
