Senior-level Citrix expertise when your team needs it.
Citrix environments are powerful, but they’re also complicated. Licensing rules shift, versions evolve, and a single NetScaler misconfiguration can disrupt the entire workforce. SötirIS provides senior-level Citrix consulting and ongoing support so your team has an expert partner whenever questions, upgrades, or issues come up.
Expertise you can depend on
60-minute response time
Citrix issues don’t wait for office hours. Neither do we.
15+ years of Citrix experience
We’ve worked with Citrix environments since the Presentation Server/XenApp era, through XenDesktop, NetScaler, and into Citrix Cloud and DaaS.
Hands-on Citrix expertise
When you call, you reach a real Citrix engineer with the experience to assess, advise, and act, not a generic support tier.
Citrix isn’t like the rest of your IT stack.
Citrix environments demand specialized expertise. The platform has its own logic around licensing, upgrade sequencing, NetScaler configuration, and profile management, and most IT teams don’t have a dedicated Citrix admin on staff.
When issues arise or upgrades loom, finding the right help quickly can be a challenge, especially for organizations outside the Fortune 500 footprint that Citrix’s largest support resources are oriented toward. That’s the gap SotirIS fills.
10+
distinct products and components in a typical Citrix deployment, each with its own versioning, lifecycle, and upgrade dependencies. This isn’t software that “just runs.”
12+
critical or high-severity NetScaler vulnerabilities disclosed since 2023, each requiring careful coordination with the rest of the Citrix environment to patch safely.

When clients call us
Most engagements start when something specific is on the horizon: a planned change, a looming deadline, or a problem that won’t resolve on its own. These are the situations where senior-level Citrix expertise pays for itself.
“We’re moving off a virtualization platform that’s gotten too expensive”
Recent licensing changes from major virtualization providers have left many organizations re-evaluating their VDI strategy. We help you plan the move, design the new Citrix environment, and guide your team through the buildout and cutover. Your team owns the infrastructure. We bring the Citrix expertise to get it right.
“Our IT team has run out of Citrix runway”
In-house IT can manage Citrix to a point. Adding users, restarting servers, basic troubleshooting. But the platform’s harder problems (NetScaler configuration, profile management, advanced policy work, performance issues) quickly outstrip generalist skills. We come in when the issue gets too advanced for the team you have.
“An upgrade is on the horizon”
Citrix upgrades aren’t a single button. NetScaler firmware, License Server, Delivery Controllers, VDAs, StoreFront. Multiple components have to move together, in a specific sequence, without breaking active sessions. We help you map the sequence, surface the risks before cutover, and stay engaged through the change.
“Licensing renewal is coming up”
Citrix licensing changes constantly: SKUs, bundles, entitlement structures, cloud-vs-perpetual decisions, partner programs. The right choice depends on usage patterns you may not have measured. We help you decode what you actually need, model the cost, and validate before you renew or restructure.
Citrix expertise without hiring a Citrix specialist
SotirIS gives your existing IT team a senior Citrix advisor on call. We help you plan upgrades, navigate licensing, secure NetScaler, and resolve issues, so your environment stays stable, supported, and aligned with where your business is going.
Guidance during upgrades
Whether it’s a Citrix version upgrade, a license server migration, or a NetScaler firmware update, we work alongside your team to plan the change, anticipate risks, and ensure nothing breaks for end users.
Support when issues arise
When something goes wrong like failed logons, slow sessions, profile issues, or NetScaler errors, we help your team diagnose root cause and get the environment back up quickly.
Strategic licensing advice
Citrix SKUs, bundles, and entitlements change frequently. We help you stay compliant, avoid overspend, and pick the licensing path that actually fits your usage. Some clients buy through us, others go direct to Citrix. Both work.
Citrix upgrades aren’t one upgrade. They’re a sequence.
Behind every Citrix version change is a coordinated upgrade of license servers, management tools, controllers, databases, and endpoints. Each piece depends on the one before it. Here’s how it actually unfolds.
License Server
Has to be ready first. New Citrix versions require compatible licensing.
Studio / Web Studio
The management interface. Upgraded before the components it manages.
Delivery Controllers
All upgraded in the same maintenance window. Mixed versions cause issues.
Site Database
Schema upgrade happens after Controllers. No going back from here.
VDAs
Updated on master images, then catalogs roll out to users gradually.
Store Front & Other
Director, Provisioning Services, and remaining components.
PARALLEL TRACK
NetScaler ADC
Runs on its own coordinated track. Firmware updates, gateway configurations, and security patches must align with the Citrix environment without taking remote access offline.

Licensing Guidance & Compliance
SKUs, bundles, and entitlements shift year to year. Our team helps you understand what you actually need, stay compliant, and avoid overspending. Some clients let us handle licensing procurement entirely, others use us to validate decisions before they buy direct.
NetScaler Expertise
NetScaler is the front door to most Citrix environments, and a frequent target. We help you plan, configure, and harden NetScaler deployments so application delivery stays reliable and remote access stays secure, with patching and best practices applied consistently.
Upgrades & Environment Modernization
Whether you’re moving to a newer version, migrating to Citrix Cloud/DaaS, or rationalizing an aging on-prem deployment, we help you scope the work, sequence the changes, and reduce risk so the upgrade doesn’t disrupt the business.
Issue Resolution & Optimization
Slow logons, broken profiles, sporadic disconnects, performance complaints—these are the issues that erode user confidence in Citrix. We help your team identify root causes, fine-tune configurations, and stabilize the environment so users stop calling the help desk.
Senior Citrix expertise, on retainer.
Our Annual Citrix Support Agreement gives your team year-round access to senior Citrix expertise. One predictable fee for the questions, day-to-day work, and smaller issues that come up. Larger projects get scoped and billed separately, so you always know what you’re paying for.
What’s included
The agreement covers ongoing Citrix advisory work: questions, smaller fixes, configuration help, version planning conversations, NetScaler config reviews, licensing guidance, and the day-to-day issues that don’t need a full project to resolve.
How you reach us
Direct access to senior Citrix engineers by phone, email, or ticket. Real expertise, not a generic tier-one queue. Our standard response window keeps you moving when something’s blocking your team.
When a project comes up
Larger initiatives (version upgrades, environment migrations, major NetScaler work, Citrix Cloud transitions) get scoped and quoted separately. You get the same team you’ve been working with, with clear cost and timing for each engagement.
Licensing flexibility
Some clients buy their Citrix licensing through us, leveraging our partner relationships. Others handle licensing themselves and use us as the expert who validates the decision. Both work. The Support Agreement is independent of how you license.
