Security compliance and audit readiness services

Security compliance and audit readiness for ISO 27001, SOC 2, GDPR, PCI DSS, HIPAA, NIS2 and DORA: gap assessments, the technical controls auditors test, policies and risk registers, and the evidence that proves each control runs, with dedicated compliance engineers for your team or a readiness project delivered up to your audit.

Compliance work we take on

  • ISO 27001 implementation

    The scope, risk assessment and Statement of Applicability for your ISMS, the Annex A controls built into your systems and processes, policies people actually follow, and an internal audit and management review completed before the certification body’s Stage 1 and Stage 2 audits.

  • SOC 2 readiness

    The Trust Services Criteria in scope chosen with you, gaps found and closed, controls running before a Type I report, and evidence gathered through the observation period a Type II report covers, ready for the CPA firm’s testing.

  • GDPR technical measures

    Personal data mapped across databases, logs and suppliers, access and erasure requests handled by the product rather than by hand, retention enforced by scheduled deletion, encryption and pseudonymisation where the risk calls for them, and records of processing and DPIAs kept current.

  • Audit fieldwork support

    A named engineer on the auditor’s request list during fieldwork: populations exported for sampling, walkthroughs of how each control works, and every exception answered with a dated remediation plan before the report is finalised.

  • PCI DSS compliance

    Cardholder data scope reduced with tokenisation and hosted payment fields, controls built to PCI DSS v4.0.1, including the inventory and integrity monitoring of scripts on payment pages, quarterly ASV scans and the annual penetration test, ready for a self-assessment questionnaire or a QSA’s Report on Compliance.

  • HIPAA safeguards

    The administrative, physical and technical safeguards of the HIPAA Security Rule built into the product: a documented risk analysis, unique user IDs, audit logs on every access to protected health information, encryption, and business associate agreements with every cloud and SaaS provider that touches the data.

  • NIS2 readiness

    The risk-management measures and incident reporting your country’s NIS2 law requires: governance approved by management, supply-chain security, multi-factor authentication, encryption, business continuity, and a reporting process that meets the national authority’s deadlines.

  • DORA ICT risk and resilience

    For financial entities and the ICT providers that serve them: the ICT risk management framework, classification and reporting of major ICT-related incidents, the register of information on ICT third-party providers, the contract clauses DORA requires, and resilience testing planned and evidenced.

  • Security questionnaires and trust centres

    Customer security questionnaires such as SIG and CAIQ answered from one maintained library of approved answers, a trust centre that shares your reports under NDA, and the controls behind each answer kept true as the product changes.

Hire compliance engineers

  • Dedicated compliance engineers

    Compliance engineers who join your team full time, work in your tools and process, and report to your lead. You interview them; we carry the Ukrainian contract, payroll, invoicing and leave.

  • Compliance engineering projects

    A defined piece of compliance engineering with a scope, a fixed plan and a named lead on our side who owns the result and reports progress in your channels.

  • Ongoing compliance engineering

    Compliance engineering as a continuing service: the same people every month, a backlog you prioritise, and hours you can see in our portal and on the invoice.

The dedicated team page explains how specialists join your team, and the outsourcing page covers project delivery, take-overs and how we charge.

    The tests auditors and standards require

How we prepare you for an audit

Certificates are issued by accredited certification bodies, SOC 2 reports by independent CPA firms and PCI DSS Reports on Compliance by QSAs; our part is the controls and the evidence they test. Work starts with a gap assessment against the standard and the scope you need, then a plan ordered by what the auditor tests first, with each control built into your systems rather than written only into a policy.

Controls are implemented as code wherever they can be: access rules, encryption, logging, backups and change approval live in Terraform and the pipelines, so the evidence is a record the system produces rather than a screenshot taken the week before the audit. We apply the same discipline to our own devices: our laptops are checked by an agent we wrote in Rust against our security baseline, on Windows, macOS and Ubuntu, with checks mapped to ISO 27001, CIS, Cyber Essentials, Essential Eight and SOC 2.

Questions about security compliance

Which industries do your compliance engineers work in?

Mostly SaaS and software companies preparing for SOC 2 and ISO 27001 because their customers ask for them; fintech, banking and insurance, under PCI DSS and DORA; healthcare and medtech products handling patient data under HIPAA and GDPR; e-commerce and retail businesses taking card payments; cybersecurity companies; and industrial, energy, hosting and telecom companies that fall under NIS2.

How long does it take to get ready for an ISO 27001 or SOC 2 audit?

It depends on the scope and on how much is already in place, so a gap assessment comes first and ends with a dated plan. A SOC 2 Type II report also needs an observation period, commonly three to twelve months, during which the controls run and leave evidence, and that period can start as soon as the controls are live.

Do NIS2, DORA and the Cyber Resilience Act apply to us?

That depends on your sector, your size and what you sell in the EU. NIS2 covers medium-sized and large entities in critical sectors through each country’s own law; DORA has applied to EU financial entities since 17 January 2025 and reaches their ICT providers through contracts; and the Cyber Resilience Act requires manufacturers of products with digital elements to report actively exploited vulnerabilities from 11 September 2026, with its main obligations applying from 11 December 2027. We map which apply to you and build the controls each one requires.

How quickly can compliance engineers start?

When the right compliance engineer is available, the start is gated only by your interview and the NDA and IP assignment. Otherwise we run a search, which typically produces candidate profiles within two to three weeks, and nobody starts until you have said yes.

How do we hire compliance engineers through BigTree108?

Tell us the work, the seniority and the hours you need. We propose one or two people with their profiles, you interview them the way you would interview your own hire, and you sign one agreement with BIG TREE 108 LLC and receive one invoice a month.

Who owns the work they produce?

You do. Every specialist has a signed contract with BigTree108 that assigns all work product to the company, and our agreement with you assigns it onward. Code, designs and documents are delivered into your own repositories and tools, not kept where only we can change them.

Preparing for an audit?

Tell us the standard, the scope and any audit date or customer deadline you are working towards. You get an answer within one business day: a scope for a gap assessment, a readiness plan, or candidate profiles.
