Every Industry Has a
Different Attack Surface.
A payment API, a clinical records system, a multi-tenant platform and a citizen service portal fail in different ways for different reasons. TMG Security adapts the assessment, the priorities and the reporting to the environment it is working in — not the other way around.

Money moves in real time. So does the risk around it.
THE ENVIRONMENT
Financial platforms carry two properties attackers care about at once: direct monetary value and high-volume automated transaction flows. The same APIs that make a payment product usable also make abuse cheap to attempt at scale, and the window between a flawed control and a financial consequence is often measured in minutes rather than weeks.
PRIMARY SECURITY CONCERNS
- Transaction and payment flow abuse, including replay, race conditions and business-logic manipulation
- Account takeover, credential stuffing and weaknesses in authentication or step-up verification
- API exposure across partner, aggregator and open-banking style integrations
- Privileged access and segregation of duties inside core banking and ledger systems
- Fraud-adjacent automation: bot-driven onboarding, card testing and mule account creation
REGULATORY CONTEXT
Financial services organizations commonly operate under card-scheme security requirements such as PCI DSS, sector regulator expectations, data protection law applicable to their jurisdiction, and contractual security obligations imposed by banking partners. TMG Security supports the technical security and readiness work that sits underneath those obligations. We do not certify, audit or provide legal advice.
Systems that cannot be switched off, holding data that cannot be replaced.
THE ENVIRONMENT
Clinical environments mix modern cloud applications with long-lived systems that were never designed to be patched frequently, and with connected devices that clinicians depend on during care. Availability is not a convenience here; taking a system offline to remediate it has a real operational cost. Health data is also permanent — it cannot be reissued the way a card number can.
PRIMARY SECURITY CONCERNS
- Exposure of patient and clinical records across applications, integrations and backups
- Legacy and embedded systems that cannot absorb frequent patching cycles
- Ransomware and availability loss affecting clinical operations
- Identity sprawl across shared workstations, rotating staff and third-party clinicians
- Health data flowing to analytics, billing and interoperability partners
REGULATORY CONTEXT
Healthcare organizations may be subject to HIPAA, GDPR, India's DPDP Act or other regional health-data regimes depending on where they operate and whose data they hold. TMG Security provides cybersecurity and compliance-readiness support for these environments. We do not provide legal advice and we do not issue regulatory approvals or certifications.
You are not defending one environment. You are defending everyone else's.
THE ENVIRONMENT
A multi-tenant platform inherits the risk profile of its customers. Ship velocity is a competitive requirement, so security has to live inside the pipeline rather than beside it. And because enterprise buyers assess their vendors, a SaaS company's security posture becomes a commercial artifact — reviewed, questioned and compared during procurement.
PRIMARY SECURITY CONCERNS
- Tenant isolation and authorization flaws that let one customer reach another's data
- Cloud and Kubernetes misconfiguration in fast-moving infrastructure
- Secrets, tokens and CI/CD pipeline exposure
- Dependency and supply-chain risk introduced through third-party packages
- Customer security questionnaires and enterprise due-diligence pressure
REGULATORY CONTEXT
SaaS companies are frequently asked to demonstrate SOC 2 or ISO 27001 alignment, and to answer data protection questions on behalf of their customers. TMG Security supports the security engineering and readiness work behind those requests. Certification decisions rest with independent auditors and certification bodies, not with us.
Peak traffic is the same shape as an attack.
THE ENVIRONMENT
Retail platforms are public by design, seasonal by nature and heavily automated at the edge. Bots, scrapers and legitimate shoppers arrive through the same front door, which makes separating abuse from demand genuinely difficult. Checkout, promotions and loyalty are where business logic and money meet, and that is usually where the interesting flaws are.
PRIMARY SECURITY CONCERNS
- Checkout, pricing, coupon and loyalty logic abuse
- Automated fraud: card testing, credential stuffing, inventory hoarding and scraping
- Payment page and client-side script integrity
- Third-party tags, plugins and marketplace integrations running in the customer's browser
- Availability and integrity during peak commercial periods
REGULATORY CONTEXT
Merchants handling cardholder data typically fall within PCI DSS scope, and consumer data is subject to the privacy law of the markets they sell into. TMG Security supports the technical assessment and readiness work in that scope. We are not a QSA, we do not perform formal certification audits and we do not provide legal advice.
Public systems answer to the public. That changes the threat model.
THE ENVIRONMENT
Public sector platforms serve citizens who have no alternative provider, hold identity data of consequence, and operate under procurement and change-control processes that move deliberately. They also attract a broader range of adversaries — from opportunistic actors to organized and sometimes well-resourced ones — precisely because the systems are visible and symbolic.
PRIMARY SECURITY CONCERNS
- Citizen identity data and the integrity of records held on people's behalf
- Public-facing service portals with wide, unfiltered exposure
- Legacy platforms and long procurement or change cycles
- Inter-departmental integrations and data sharing between agencies
- Continuity of essential services and resilience against disruption
REGULATORY CONTEXT
Public sector environments operate under national data protection law, government security guidance and the specific requirements written into their procurement contracts. TMG Security supports technical security assessment and hardening work within those frameworks. We hold no regulatory authority, make no claim of government accreditation, and do not provide legal advice.

Which categories tend to demand attention where.
A qualitative view of where security effort is commonly concentrated by sector. It is a starting point for a conversation, not a measurement of any specific organization.

Security priorities vary by organization, architecture and threat model. This matrix is illustrative.
Sector-specific risk still resolves to the same layers.
Whatever the industry, work has to land somewhere in this stack. The sector determines the order in which the layers are addressed and how much weight each one carries.
ILLUSTRATIVE MODEL · LAYERS ARE ADDRESSED IN THE ORDER THE ENVIRONMENT REQUIRES
What changes between one industry and the next.
The methodology is consistent. The inputs to it are not.
Where each industry usually starts.
Highlighted for the industry selected above. Dimmed entries remain available — they are simply less often the first engagement for that sector.
The kind of problem each environment tends to produce.
Illustrative situations that describe common patterns in each sector. These are not case studies and do not describe any specific client, engagement or outcome.
A payment API is functionally correct but allows a request to be replayed before the idempotency check settles.
A records integration exposes more fields than the receiving system needs, and nobody owns the decision to narrow it.
An authorization check validates that the user is logged in, but not that the record belongs to their tenant.
A discount rule is enforced in the storefront but not re-validated server-side when the order is submitted.
A portal built for one department is reused by another, carrying an access model that no longer matches who is using it.
Depth in the sector. Range across the problem.
Context before tooling
The environment decides the approach. We start from how the organization operates, not from a standard checklist applied uniformly across every sector.
One team across the lifecycle
Offensive testing, defensive operations, cloud, product security and GRC sit under the same roof, so findings do not have to be re-explained at every handoff.
Evidence, not assertion
Every claim in a deliverable is traceable to something observed. Where we are uncertain, the report says so rather than rounding it up.
Built to be handed over
The measure of an engagement is what the internal team can do afterwards without us in the room.
