Rocket Host Access

Mainframe security has long carried a reassuring reputation: stable, resilient, and secure by design. But the conversation has shifted. Today, the biggest risks aren't tied to the platform itself – they're tied to how users access it. Three themes are emerging with increasing urgency across the industry: uneven MFA adoption, modernization efforts centered on identity controls, and regulatory frameworks making strong authentication non-negotiable. Together, they reveal where mainframe security is heading – and where the gaps still remain.The MFA gap is becoming harder to ignoreOrganizations have made real progress on MFA adoption, but the finish line isn't in sight yet. Around 83% still rely on passwords for at least some systems, and a meaningful share of users remain without full MFA coverage. That gap has real consequences: stolen credentials now account for roughly 22% of breaches, making identity the single most common initial attack vector.For mainframe teams, this dynamic is fami

In highly regulated industries like finance, healthcare, and government, securing remote access to mission-critical legacy systems is a top priority. When you deploy Rocket® TE Security Server, most of your attention naturally focuses on configuration. You spend time locking down connections, enabling encryption, and ensuring seamless integration with your identity and access management (IAM) solutions.But there is a critical, often overlooked task that can make or break your compliance posture: backing up your security server configuration.While it rarely feels urgent, having a reliable backup is the difference between a rapid recovery and a long, painful rebuild. Let us explore why making backup a routine part of your operations is essential for disaster recovery, compliance readiness, and secure host access management.The hidden risk of neglecting your security server configurationOnce your security server is configured and running, it is tempting to treat it as a finished project.

Host Access NewsWe’re already one quarter into 2026, and there have been so many developments in regards to AI. I have to imagine the majority of us are using AI tools on a daily basis. From OpenAI, to the coding power offered by Claude, to the potential security capabilities of the new Mythos, it’s exciting to see the power at our fingertips. Sadly, not everyone using these tools has the best intentions, and we’re already seeing very real cybersecurity threats powered by these tools.If it’s not already clear, you need to be thinking about how these AI tools impact the security of user access in your mainframe-based environment. Security by obscurity isn’t enough.But let’s look at some of those real-world scenarios that have already begun to play out.Claude tried to hack 30 companies – but no one asked it to.A cybersecurity firm recently took on the research task to answer the question: what if we asked Claude to research certain data that could only be retrieved via hacking? The resul

When you manage mission-critical IT infrastructure for finance, healthcare, or government organizations, secure remote access is a strict necessity. You face constant pressure to pass security audits, integrate identity and access management (IAM) solutions, and meet looming government compliance deadlines. However, many legacy host systems do not natively support modern security protocols like SSL or TLS, leaving a critical gap in your defense-in-depth strategy.You know your organization needs to modernize its security posture without disrupting daily operations. Rocket TE Security Server steps in as a key player to fill this gap. It provides a robust, flexible, and user-friendly way to encrypt connections for terminal emulation clients. Let us take a closer look at the architecture of Rocket TE Security Server and the system prerequisites you need to check before rolling out a secure deployment.How the security server works as a secure proxyAt its core, Rocket TE Security Server func

Hello Team, Good day! I need help with refelection - excel vba macros automation.In our project we want to navigate to specific screen in reflection workspace application and copy all the needed data from that screen to excel sheet by using excel vba marcos automation. Kindly guide me to achieve this. #reflectionbasicmacros#Macro#macroeditor#ReflectionX#Reflections#Office#Vba#Windows#Desktop#Reflection#Other#Excel

Mainframes, iSeries, and UNIX systems remain critical in finance, healthcare, and government. Securing remote access isn’t optional—it’s required by strict regulations. The challenge: many legacy hosts don’t support modern security like SSL or TLS, forcing IT teams to find solutions that won't disrupt operations or create downtime.Rocket TE Security Server bridges this gap. It’s a Windows-based proxy that enables robust SSL/TLS encryption for Rocket TE clients, acting as a secure intermediary between clients and host systems. This allows encrypted tunnels for remote sessions, giving admins control over which connections are encrypted, based on compliance needs—all without touching the original legacy code.Dual-mode flexibility for your networkRocket TE Security Server adapts to different environments through two modes:SSL to clear-text proxy: Rocket TE clients connect securely via SSL, with traffic decrypted at the server before reaching hosts that can't process SSL/TLS. This protects

Hi,I’ve been running into a bit of a frustrating hurdle while trying to modernize some of our older terminal workflows, and I’m curious if anyone here has found a reliable workaround. We’re attempting to automate a series of data entry tasks, but we keep hitting these intermittent execution timeouts. It seems like the emulator is losing its "focus" mid-script, which causes the whole automation string to just hang indefinitely until I manually refresh the session.I’ve spent the morning looking into whether this is a resource allocation issue on the host side or if I just haven't configured the background processes correctly. I even tried a fresh delta download of our execution toolkit to see if updated libraries would resolve the handshake errors, but the script still seems to struggle with the timing between the commands and the UI response.Has anyone else dealt with this kind of lag or "ghost" hanging during high-volume script runs? I’m starting to wonder if it’s a specific setting wi

I am moving from Bluezone to Rocket TE and do not have macros in Rocket.  Is there a means to convert my bluezone VBA macros to a script that can be used with Rocket TE?

Our team uses an Excel VBA macro to automate actions through Rocket Terminal Emulator (BlueZone). It was created on machines and is used by users that have Excel 32‑bit and the macro runs without any issues. New team members, however, are on Excel 64‑bit, and they are all getting the following error: Have anyone one else had similar errors and what was your solution?

Host Access NewsWe’re inching closer to the end of 2025, and it’s been a busy year in cybersecurity. A new threat has emerged in the form of fake IT workers, with related charges brought against individuals in the United States. At the same time, state-sponsored and AI-powered attacks continue to grow. The need for in-depth defense is more critical than ever. Whether you’re mitigating the risk of the next potential attack or securing systems to comply with the latest regulations, it’s important to know where your blind spots are. New Rocket® Host Access Forum If you haven’t seen it yet, check out the new Rocket® Host Access Forum.

There doesn't seem be a lot of good (modern/supported) solutions for the Mac in the 3270 emulation space.  Passport for Host Access on Windows is great, but let down by having to "remote" into a Windows Platform to run it.  I've seen plenty of "web based" emulator options offered, but running 3270 emulation in a browser tends to miss on the important productivity features, like good keyboard mapping, script support etc. I have had some success in the past with W.I.N,E and CrossOver (emulating the required (Windows) functions/APIs, but not an option due to security concerns at my shop.  Is Rocket looking to port to a native client? - What is everybody else using, while we wait?------------------------------Eoin O'CleirighANZ Banking Group LimitedMelbourne VIC AU------------------------------

I have recently observed that the Proxy Shell service on a Windows Server stops unexpectedly, with no logs indicating the cause. However, performing a reboot temporarily resolves the issue, although it reoccurs after a few days. When creating a job in Gateway Administrator targeting file servers where the directory is set to the root ("/"), the job does not seem to detect or transfer any files. Could someone please assist with this issue? ------------------------------Moroka Frank TapalaMrRocket Forum Shared Account------------------------------

Hi everyone, I'm very new to Host Access and D3. We're currently working in a D3 Pick environment using the TCL (Terminal Command Language) prompt, and I need to learn everything from scratch. I do have access to Rocket Software's D3 reference manuals, but they're quite large and a bit overwhelming to read cover to cover. Could anyone please suggest the best places to find learning materials - especially video tutorials that cover basic concepts, TCL commands, creating simple programs, and understanding how everything works with real examples? I really prefer videos or more practical, hands-on resources rather than just manuals. Thanks so much in advance for your help!------------------------------Rima PrajapatiSenior IT SupportRocket Software Forum Member------------------------------

My Rocket TE Secure FTP client is almost unusable.  I think it has something to do with the VMS version numbers. There is a {hh:mm} or {yyyy} in front of each and every remote file.  So, if I download that file to my PC, the filename on my pc will have that {hh:mm} or {yyyy} timestamp in the filename. "X.TXT becomes "05:17 X.TXT". Double-clicking on sub-folders generates an error because subfolder "/DISK3/05:17 TEMP" does not exist.

If you use Rocket Reflection Desktop to connect to hosts, you know that setting up your sessions just the way you like can save a lot of time. With a few simple options, you can make your sessions connect automatically, reuse favorite settings, keep your data secure, and even launch sessions directly from the command line. Here's a quick guide to make your Reflection experience even smoother. Control When You Connect By default, Reflection Desktop likes to help out by connecting you to your host automatically whenever you create or open a terminal session. But sometimes, you might want a little more control. Want to open a session and connect later? You can easily turn off the auto-connect feature. Just open your session and head to the Settings. If you're using the Ribbon or Browser mode, click the gear or Document Settings icon. On TouchUx, tap the Gear icon and select Document Settings. Find the Host Connection section, click "Configure Connection Settings," and then uncheck "Automa
