South San Francisco runs on regulated electronic records - the batch that shipped, the result that released it, the signature that approved it - and an attacker who can quietly alter one of those is a data-integrity event, not just a breach. CyberFortify runs manual OT/ICS, network, web and cloud penetration tests on GxP manufacturing and lab systems here, aligned to NIST CSF, 21 CFR Part 11, GAMP 5 and ALCOA+. Change-control-aware, validated-state-safe, delivered remotely from our Gulf base on a daily overlap window. Fixed price, audit-ready reporting, free retest.
// 01 Why South San Francisco biotech needs penetration testing
The value in a South San Francisco plant is not only the molecule - it is the evidence that the molecule was made correctly. A release decision rests on a chain of electronic records: the weigh step captured in the MES, the assay result posted in the LIMS, the chromatogram sitting on an instrument PC, the electronic signature that approved the batch record. Regulators do not just want that product to be safe; they want to trust the records that say it is.
That makes this market different from ordinary IT. An attacker who can edit a result, suppress an audit-trail entry, or sign as someone else does not merely leak data - they undermine a regulated record, which can invalidate a batch, trigger a data-integrity observation, or put a patient at risk. The threat is quiet manipulation of trusted records, not the noisy exfiltration a generic pentest looks for.
Scanning cannot see this. A scanner flags an unpatched instrument controller; it cannot tell you that an operator role can disable the audit trail before making a change, that a LIMS test method can be edited without a second review, or that a historian shares a service account reaching the manufacturing floor. Those are authorisation and integrity failures inside validated systems, and confirming them takes a tester who understands both the exploit and the GxP context around it.
// 02 Compliance and regulatory drivers in South San Francisco
Life-science manufacturers answer to a records-integrity regime that most other industries never touch. These are the requirements we most often map findings against, written so your quality and validation teams can lift them straight into their files.
FDA 21 CFR Part 11 - records & signatures
Part 11 sets the controls for electronic records and signatures: protected audit trails, signature-to-record binding, access limits and copy integrity. We test whether each control actually holds under attack, not just whether it is configured.
GAMP 5 / CSV
Computerized-system validation assumes the qualified system behaves as specified. Our testing probes the gaps validation does not - privilege abuse, injection and logic flaws - inside change control so the validated state is preserved.
ALCOA+ expectations
Attributable, Legible, Contemporaneous, Original, Accurate - plus complete, consistent, enduring, available. We test whether a record's authorship, timestamp and original value can be forged or altered without trace.
EU Annex 11
Product sold into Europe brings Annex 11's computerised-system controls alongside Part 11. Its expectations on access management, audit trails and data storage overlap heavily, and we map to both where you export.
// 03 Penetration testing services for South San Francisco
Engagements here weight the regulated systems - the LIMS, MES, historians and instrument PCs that carry electronic records - and the IT/OT boundary that is meant to keep the manufacturing floor separate from the corporate network.
OT/ICS pen testing
Manufacturing floor systems, historians, instrument controllers and IT/OT segmentation - tested with the caution qualified, safety-relevant environments demand.
Network pen testing
Active Directory, segmentation between GxP and corporate zones, and the service accounts historians and integration engines share across them.
Web application pen testing
LIMS, MES and quality-system web front ends - authorisation, segregation of duties, e-signature workflows and business-logic abuse against the OWASP Top 10.
Cloud pen testing
Identity, tenant isolation and storage exposure across validated cloud and GxP SaaS hosting batch records, lab data and regulatory documents.
API pen testing
The interfaces linking LIMS, MES, ERP and instrument systems - broken object-level authorisation, scope enforcement and token handling between regulated apps.
Source code review
For in-house lab and batch software, review of authorisation logic, audit-trail writes and signature handling where a defect would break Part 11 by design.
// 04 How we deliver to South San Francisco
We will not pretend otherwise: CyberFortify is a Gulf-based firm on UTC+3, and South San Francisco sits ten to eleven hours behind us. We have no California office and no local staff. What we bring instead is a working pattern built for regulated environments - our late afternoon and evening is your morning, held open daily for stand-ups, change-window coordination and read-outs with your validation and quality teams. Testing runs while your site is quiet, which fits manufacturing schedules where the safest windows fall outside production.
What runs remotely
Web, cloud, API and external testing, plus assessment of staging and non-GxP mirrors, from our secure environment - the majority of scope for LIMS, MES, quality and lab-software targets. Confirmed findings land in a shared channel, and critical issues are escalated at once.
What we do on-site
Internal network, segmentation and manufacturing-floor OT testing where a tester genuinely needs to be on the wire, plus workshops with validation and quality committees. We travel when it adds value and say so when it does not.
Every engagement opens with a free 30-minute scoping call and a fixed-price quote within the hour. For validated and production systems we agree change-control windows and non-GxP mirrors up front, and a free retest proves each fix without reopening the change.
// 05 Industries we secure in South San Francisco
South San Francisco's risk profile is defined by the densest concentration of life-science manufacturing and laboratories in the country, and the technology vendors that serve it.
// 06 Our methodology
South San Francisco engagements follow the same audit-defensible process we run everywhere, tuned to systems that must stay validated. Testing is grounded in PTES and NIST SP 800-115, with exploitation mapped to MITRE ATT&CK tactics and application work driven by OWASP. Every action is change-control-aware: we work against qualified mirrors and agreed windows, and we do nothing that would force requalification. As a CREST Accreditation Pathway firm we lead with manual testing - automation supports the tester, never replaces one.
Scoping & change control
Targets, validated boundaries, non-GxP mirrors, test windows, seeded records and escalation paths agreed in writing before a packet is sent.
Fixed quote in 1hReconnaissance & threat modelling
Attack surface mapped around the record itself - who can create, edit, approve or delete it, with which privileges, and where the audit trail can be reached.
ATT&CK alignedManual exploitation
Audit-trail bypass, e-signature abuse and segregation-of-duties flaws exploited under controlled conditions, proven with seeded records - never live batch or patient data.
Validated-state safeReporting & free retest
Executive summary, CVSS-scored detail and mapping to 21 CFR Part 11, GAMP 5, ALCOA+ and NIST CSF - plus a free retest once your CSV change ships.
Audit-ready// 07 Why CyberFortify for South San Francisco
A scan-and-report vendor
Automated output rebadged as a penetration test, blind to Part 11 controls and liable to trip a qualified system into an unvalidated state - the last thing your quality team can accept before an inspection.
CyberFortify
A Gulf-based, CREST-pathway team candid about the time difference and structured around your change windows. Manual exploitation aimed at audit-trail, e-signature and segregation-of-duties failures, findings mapped to the frameworks your inspectors read, fixed pricing and a free retest.
Engagements here most often pair a LIMS or MES application assessment with network and segmentation testing, since a validated system's risk splits between its own authorisation logic and the IT/OT boundary around it. Where an instrument or historian reaches the manufacturing floor, we add OT/ICS testing to check that segmentation holds under a real intrusion.
// 08 Frequently asked questions
Can you test our LIMS and MES without breaking their validated state?
Yes - preserving validated state is the constraint we design the engagement around. We test against a qualified staging or non-GxP mirror wherever one exists, and where production access is unavoidable we work inside agreed change-control windows with read-only or seeded-record boundaries. We do not alter configuration, load unmanaged agents onto qualified hosts, or take any action that would force requalification. Every step is logged so the work slots cleanly into your change record rather than reopening it.
How do you test 21 CFR Part 11 audit trails and electronic signatures?
We attack the controls Part 11 depends on rather than accepting that they are switched on. We test whether audit trails can be disabled, edited or bypassed by a privileged operator, whether records can be altered without a corresponding trail entry, and whether the system clock or record sequence can be manipulated. On electronic signatures we test signature-to-record binding, re-use of a session to sign as another user, and whether the two signature components can be captured or replayed. Each finding is written against the specific Part 11 clause it undermines.
Which regulations and standards drive penetration testing for South San Francisco biotech?
FDA 21 CFR Part 11 governs electronic records and signatures, and GAMP 5 frames computerized-system validation, with ALCOA+ setting the data-integrity bar that inspectors read your systems against. EU Annex 11 applies to product sold into Europe. HIPAA reaches any clinical-trial or patient data you hold, card handlers add PCI DSS 4.0, and many manufacturers anchor the wider security programme to NIST CSF. We map every finding to the framework your quality and inspection teams already answer to.
With your team in the Gulf, how does the time gap work for a South San Francisco engagement?
We will be plain: CyberFortify is a Gulf-based firm on UTC+3, ten to eleven hours ahead of South San Francisco, with no California office or local staff. We hold a deliberate daily overlap window - our late afternoon and evening is your morning - for stand-ups, change-window coordination and read-outs with your validation and quality teams. Testing continues while your site is offline, which suits manufacturing schedules where the safest test windows fall outside production hours.
Will the report be usable in a data-integrity or inspection-readiness file?
That is what it is written for. You get an executive summary, CVSS-scored technical detail, and findings mapped to 21 CFR Part 11, GAMP 5, ALCOA+ and NIST CSF so it drops straight into a data-integrity assessment or inspection-readiness pack. Book a free 30-minute scoping call and we return a fixed-price quote, usually within the hour, and a free retest confirms each remediation once your CSV change ships.
