Proven with Industry Leaders
Duczer East's integration practice predates our AI work — and that's exactly why our AI solutions succeed where others stall. We've spent years connecting complex enterprise systems across API gateways, event-driven architectures, and identity platforms. When AI agents need to securely access a trading system, pull real-time data from a claims engine, or authenticate across microservices, DE already knows how those systems work. We meet clients where their infrastructure lives — whether that's WSO2, MuleSoft, Apigee, or something built in-house. Our WSO2 consulting practice goes deepest, and our agentic integration work governs the AI agents now moving through that layer. And when the platform you run needs coverage or hands, our WSO2 support services keep it healthy and staffed.
System integration services for regulated enterprises
For a bank, insurer, or health system, integration is also a control surface: every API, identity flow, and data stream has to be secured, monitored, and explainable to an auditor. Our services cover five areas, below. The sixth, governing AI agents as they call your systems, is our agentic integration practice.
APIs That Scale With Your Ambition
Well-designed APIs are the connective tissue of modern enterprise architecture — and the gateway through which AI agents access your systems. DE brings deep expertise in API strategy, design, and lifecycle management across the platforms your teams already use.
Whether you're rationalizing a sprawling API estate, designing new services for AI consumption, or migrating between gateways, Duczer East has done it before — at scale, in regulated environments, under tight timelines.
- API strategy, design, and governance
- Gateway implementation and migration
- API security, rate limiting, and policy enforcement
- Developer portal and API marketplace design
- Platform-flexible: WSO2, MuleSoft, Apigee, Kong, Boomi, and others
Securing How AI Agents Operate in Your Enterprise
As AI agents proliferate, a new security challenge emerges: how do you govern what an agent can access, what actions it can take, and on whose behalf it's acting? This isn't traditional IAM — it's a new discipline, and DE is leading it.
Built on our deep IAM/CIAM foundations, Duczer East's Agent Access Management practice defines the policies, authentication flows, and authorization boundaries that keep AI agents productive without becoming a risk. We implement across identity platforms — not just one vendor — so the solution fits your existing security architecture.
- AI agent authentication and authorization frameworks
- Policy-based access controls for agent actions
- Delegation chains — governing "on behalf of" scenarios
- Audit trails and compliance logging for agent activity
- Integration with existing IAM/CIAM infrastructure
Real-Time Data for Real-Time Decisions
Batch processing can't keep up with AI that needs to act now. DE designs and implements event-driven architectures that move data as it's created — enabling AI agents, dashboards, and downstream systems to operate on current reality, not yesterday's snapshot.
This is core DE DNA. Our streaming implementations power clinical systems, trading platforms, and logistics operations where latency isn't measured in hours — it's measured in milliseconds.
- Apache Kafka implementation and optimization
- Event sourcing and CQRS patterns
- Change data capture (CDC) for legacy system integration
- Stream processing and real-time analytics
- Message queues: RabbitMQ and other MQ products
- Loosely coupled microservices architecture
From Monolith to Modern — Without the Drama
Legacy systems aren't just technical debt — they're barriers to AI adoption. If your data is trapped in monolithic applications and tightly coupled architectures, no amount of AI tooling will unlock its value.
Duczer East has a proven track record of migrating legacy systems to modern, cloud-native architectures. Our framework and AI-assisted tools accelerate the process — DE has demonstrated completion in 55% of the time compared to traditional approaches.
- Monolithic-to-microservices decomposition
- Cloud-native migration strategy and execution
- AI-driven requirements analysis and code assessment
- Low-code development acceleration
- Incremental modernization — evolve without disrupting
Connecting Everything — Cleanly
Enterprise systems don't exist in isolation, but too often they operate that way. DE's integration practice connects SaaS platforms, on-premise systems, databases, and AI services into a coherent data fabric that eliminates silos and enables automation.
From Salesforce to ERP systems to custom microservices, Duczer East builds integrations that are maintainable, observable, and ready to feed AI — including customer data platform capabilities where they add value to the overall architecture.
- SaaS-to-SaaS and SaaS-to-on-premise integration
- Data transformation and orchestration
- Salesforce and CRM integration
- Automated marketing platform connectivity
- Customer data platform capabilities within the integration layer
We Meet You Where Your Infrastructure Lives
DE doesn't force you onto a single vendor. We implement and integrate across the platforms your teams already rely on. For the operations layer, our ServiceNow ITOM consulting practice connects detection to managed, auditable action.
How a system integration engagement runs
Most engagements start with a short, fixed-scope assessment of the integration estate and move through four stages. You can start at any of them, in English, Spanish, or Portuguese.
Assess
Map the systems, interfaces, identity flows, and data movements you run today, and where they break or fail an audit.
Design
Target architecture: which platform owns APIs, events, and identity, and how policy and evidence are enforced across them.
Build
Implement in phases, with the old and new paths running side by side until each cutover is proven.
Run
Support, managed integration services, an outsourced integration team, or engineers for the roles you need filled once the integration layer is live.
Integration platform or custom middleware?
An integration platform, whether an API manager, an iPaaS, or an event broker, gives you reusable connectors, policy enforcement, monitoring, and vendor support. Custom middleware gives you full control, but you own every line of code, every patch, and the knowledge when its author leaves. For regulated enterprises we usually recommend a platform for the governed core of APIs, identity, and events, and custom code only where a platform cannot do the job. Where WSO2 is the platform, our WSO2 consulting practice goes deepest.
System integration partner types compared
Each kind of integration partner fits a different situation. The table describes fit, not rank.
| Partner type | Where it fits | Where it falls short |
|---|---|---|
| Duczer East (specialist integration partner) | Regulated enterprises that need API management, identity, and event-driven integration designed, built, and supported by one senior team across the Americas. | A smaller bench than a global integrator. Not the right choice for a program staffed by hundreds. |
| Platform vendor professional services | Deep knowledge of one product and the closest view of its roadmap. | Scope stops at that vendor’s product, while most estates run several platforms and in-house code. |
| Global systems integrators | Large multi-platform programs that need scale, global coverage, and one contract across many workstreams. | Integration depth varies by team, the senior people in the sale may not do the work, and the cost structure is higher. |
| Single-platform specialists | Fast delivery on the one integration platform they resell or specialize in. | The answer tends to be their platform. Check how they handle identity, events, and systems outside it. |
| Offshore delivery teams | Cost-efficient capacity for well-specified build and run work. | Time-zone distance from your teams, and security and regulatory context need checking before work starts. |
System integration, answered plainly.
What are system integration services?
System integration services connect an organization’s applications, data, and partners so they work as one system. For an enterprise that covers API design and management, identity and access, event-driven and real-time data flows, connecting SaaS and on-premises systems, and modernizing legacy platforms so they can be integrated at all.
What is integration consulting?
Integration consulting is the advice and design work on how systems should connect: which platform owns APIs, events, and identity, how existing interfaces are rationalized or replaced, and how security and audit requirements are enforced. It usually starts with an assessment of the estate and ends in a target architecture and a phased plan, which your team or ours can then build.
How do you choose a system integration partner?
Test five things: senior engineers doing the work rather than only selling it, hands-on experience with the platforms you run, depth in identity and security as well as APIs, references in regulated environments if you operate in one, and whether the partner will recommend a platform other than the one it resells.
What is the difference between an iPaaS and custom middleware?
An iPaaS or integration platform gives you prebuilt connectors, policy enforcement, monitoring, and vendor support. Custom middleware gives you full control, but you own every line of code, every patch, and the knowledge when its author leaves. Most regulated enterprises are best served by a platform for the governed core and custom code only where a platform cannot do the job.
What are managed integration services?
Managed integration services keep an integration estate running and changing after go-live: monitoring, incident response, patching and upgrades, and the changes the business keeps asking for. Duczer East provides them as an outsourced integration team, with a persistent senior core, capacity added on an agreed lead time, a shared knowledge base, and monitoring from our network operations center.
When does an outsourced integration team make sense?
When the estate needs continuous development as well as support, and a full in-house integration group would cost more than the work justifies. A persistent core of senior engineers carries the run, and capacity is added for initiatives and released when they land. It suits organizations whose integration demand comes in waves.
How do you monitor APIs and integrations in production?
From our network operations center. For the estates we manage, the NOC monitors APIs, integrations, and message flows, catches failures and slowdowns, and routes them to the engineers who know the estate, so issues are handled before they reach users or partners.
How long does an enterprise integration project take?
It depends on the number of systems, the state of the interfaces you have today, and your security and audit requirements. A single API or event flow can go live in weeks; replacing a legacy integration layer is a phased program measured in months. We size it after a short assessment of the estate.
What does system integration cost?
It depends on scope: the number of systems and interfaces, the platforms involved, and how much of the build and run your own team will carry. We scope each engagement after the assessment rather than quoting a rate card.
Which integration platforms does Duczer East implement?
WSO2 is our key partner platform for API management, integration, and identity. We also implement and support MuleSoft, Apigee, Kong, and Boomi, Apache Kafka for event streaming, RabbitMQ and other message queue products, Salesforce integration, and integration services on AWS and Azure, and we work with in-house middleware where that is what you run.
