General Questions about the NCP Secure VPN Clients

  • Which client software does NCP offer?

    NCP offers Secure Entry clients and Secure Enterprise clients for universal access to central data networks. Both support all security technologies (VPN, PKI) and use the same communications and security standards. The latter can be administered centrally and can be bundled with the NCP Endpoint Security concept.

  • What are the differences between NCP Secure Entry Client and NCP Secure Enterprise Client?

    All clients have a similar range of features, but the NCP Secure Enterprise Client can also be administered centrally. You'll find a features' comparison here.

  • How do I get the latest version of NCP secure clients?

    Easy. Go to the NCP Download Area.

  • How do I update my NCP Software?

    Updates can be free-of-charge or they must be purchased. This depends on whether the new software has new features:

    • Updates are free of charge if a new minor release is introduced on the market , e.g. V. 10.00 to V. 10.04
    • Updates must be purchased if a new major release is introduced on the market, e.g. V. 10.10 to V. 11.10

    Up to version 10 major releases were indicated by changing the first number after the decimal point, e.g. from version 10.00 to version 10.10.

    From version 11, major releases will be indicated by incrementing the complete version number, for example version 11 to version 12.

    Major Release

    Major releases contain significant changes; i.e. extensions in performance and function that are not error corrections.
    Must be purchased: New license key

    Minor Release

    Minor releases contain error corrections and minor improvements.
    No-charge: No new license key (LK) is required

    The license key version must be equal to version number.

    Here you find all fee required Major Releases

    Important note:  There is no duty for Updates

  • Where can I find the information of the current version I use?

    You can find the information at the Client Monitor. Click on "Help" at the menu bar and choose "Info".

  • Does the NCP secure client also work with VPN gateways from third-parties?

    Yes, based on the IPSec standard, incl. all RFC protocol enhancements (XAUTH, IKEConfig, NAT-T).

    However, some VPN vendors may have different IPsec implementations or not support specific IPsec extensions. Please contact the vendor of your IPsec gateway with questions regarding specific features.

  • Is there a way to easily import client configuration files from other vendors?

    Yes, you can automatically import .pcf, .wgx, .spd or .ini files.

  • Can I also log in to a domain via GPRS/UMTS using NCP secure clients?

    Yes. You'll find details here.

  • How does the NCP client provide secure Hotspot logon?

    Yes, you'll find details in the PDF "Entry Client Mobile Computing"
    (The links may only be opened within the manual.)

  • I'd like to set up a (really) secure VPN connection without being at the mercy of the Internet or public WLAN. Is that possible with the secure client from NCP?

    Yes. NCP secure clients have an integrated, dynamic personal firewall and support FND (Friendly Net Detection). Find out more here.

  • Does the Entry client recognize friendly networks and choose different firewall settings automatically?

    Yes, you'll find details in the PDF " Entry Client Firewall and FND"
    (The links may only be opened within the manual.)

  • Does the NCP solution address the issue of overlapping IP networks?


  • Is there a possibility to lock the settings for VPN, Internet Access and Personal Firewall in order to prevent users from misconfiguration?

    You'll find details about the NCP Secure Entry Client in the PDF "Entry Client Monitor"
    (The links may only be opened within the manual.)

    You'll find details about the NCP Secure Enterprise Client in the PDF "Enterprise Client Monitor"
    (The links may only be opened within the manual.) 

  • What happens if you unplug an external certificate storage device (e.g. smartcard, USB flash drive, SD card)?

    The VPN connection is immediately and automatically disconnected if the default setting is still in place. If the VPN connection is to remain, you can configure this specifically. 

  • Do I need a personal firewall for mobile computing as well as the NCP secure client?

    No. All VPN clients from NCP have an integrated personal firewall which can also be administered centrally in the case of the Secure Enterprise client.

  • If you already use a NCP VPN client and need to install the client software on a new end device, you can easily transfer your client settings. In order to do so, you only need to copy the file "ncpphone.cfg", which contains all settings of the NCP client. You can find this file when you follow the paths listed below (Link/PDF of the listed paths):

Questions about the NCP Secure VPN Clients and Windows

  • Windows 10 Anniversary Update and Secure Boot?

    With the Windows 10 Anniversary Update announced for August 2nd, 2016 a fresh installation of all older released NCP Secure Client version will fail should Secure Boot be enabled in the system’s BIOS/UEFI settings. In this combination, Windows now requires signed driver by Microsoft. Until now it was sufficient merely for the driver to be signed by the manufacturer. For this reason a new version of the NCP Secure Client with appropriate signature is available now. A system upgrade to the Windows 10 Anniversary Update, with a previously installed NCP Secure Client does not affect the functionality of the client.

  • Windows 10 Update 1511 (Threshold 2/Build 10586) causes problems with installed NCP Secure Client

    Microsoft’s november update for Windows 10 is far more than merely a collection of patches and/or enhancements. In general it is essentially a new version of Windows. Some areas of the registry database are rewritten during the update and while doing so a few important entries of the NCP Secure Client are discarded.

    To resolve this issue the lost registry keys and related values have to be written again. Therefore one has to perform an uninstall of the NCP Secure Client followed by a mandatory reboot prompted for within the uninstall procedure. After which one just has to reinstall the version of the client used before. (Please do not confirm the “Delete all files“ option of the uninstall process).

    The full configuration will be preserved; only the license information has to be re-entered after the installation. After having completed this procedure the NCP Secure Client can be used again without any limitations.

  • What do I have to consider when updating from Windows 7 or 8 to Windows 10?

    When updating from Microsoft Windows 7, Windows 8 or Windows 8.1 to Microsoft Windows 10, it is vital that the NCP Secure Client be uninstalled before starting the update.

    At the same time it is recommended that the configuration file, as well as the certificates used, is saved separately.

    After the Upgrade to Windows 10 is completed, make sure to install version 10.02 (or later) of the NCP Secure Client as previous versions are not supported for Microsoft’s most recent OS.
    Please note that a license key version 10.0 is required to run version 10.02 of the NCP Secure Client on Windows 10.

  • What do I have to consider when updating from Windows 7 to Windows 8?

    Under certain circumstances , when the operating system is upgraded from Windows 7 to Windows 8, the NCP Secure Client no longer works after the upgrade. In such a case, download the latest version of the NCP Secure Client from the NCP website and install this over the existing version of the Secure Client; afterwards the Secure Client software should work correctly.

  • Is the NCP Secure Client supported on Windows 8 RT and Windows Phone 7/8?

    Currently NCP provides VPN Clients for Windows 10, 8, 7 and Windows Mobile 5/6.x. For the other Windows OS we provide our SSL VPN solution (Web Proxy).
    NCP also plans to provide IPsec VPN Clients for Windows 8 RT and Windows Phone 7/8, Microsoft’s new operating systems. However, due to technical restrictions imposed by Microsoft, NCP is not currently able to develop Secure Client versions for these operating systems. The information required from Microsoft is not yet available.

  • Do NCP's Secure Clients support WWAN Hardware (Wi-Fi, 3G) with NDIS 6.2 driver for Windows 7 (e.g. Sierra Wireless, Huawei, Option)?

    Yes, they do. The architecture of NCP's Secure Clients allows for a smooth VPN connection. 

Questions about the NCP Secure VPN Clients and OS X, macOS, iOS

  • Updating to macOS 10.16

    Starting from macOS Catalina 10.15.4, a message is displayed about the "NCP engineering GmbH" kernel extension. This kernel extension is necessary for the correct operation of the NCP Secure client on macOS. We do not recommend updating to macOS 10.16 (expected to be available in autumn 2020) until NCP provides a new version of the NCP Secure Client compatible with macOS 10.16.


  • The NCP Secure Entry Mac Client V 2.05 Rev 32042 for macOS 10.12 Sierra shows an English GUI on a German desktop. How can I fix this?

    To show the client GUI in German on macOS Sierra, close and restart the GUI and enter the following in macOS terminal under Programme/Dienstprogramme/Terminal: defaults write com.ncp-e.ncpmon Language 1

  • What do I have to consider when updating from OS X 10.10, 10.9 or 10.8 to OS X 10.11 El Capitan?

    If the NCP Secure Client for Mac is installed on an older operating system, e.g. OS X 10.10, and you update to OS X 10.11 El Capitan, an error message could appear indicating that the NCP Secure Client cannot access the log. The user can fix this malfunction by entering the following command in the command line: sudo chmod 777 /Library/Logs/NCP. Otherwise you can uninstall the NCP Client before the update and install it again after the update.

  • Is the NCP Secure Mac OS X Client release 2.02 build 14 compatible with the Mac OS X 10.8 Mountain Lion operating system?

    In priniciple, the NCP Secure Mac OS X Client release 2.02 build 14 is compatible with Mac OS X 10.8 Mountain Lion. However, the "Gatekeeper" security feature, newly introduced with Mountain Lion, must be disabled before starting a new install or update of the NCP Secure Client. Before starting the install routine, the OS X System Preferences must be modified: under "Security & Privacy/General" temporarily change the setting of "Allow applications downloaded from" to "Anywhere".
    As soon as the installation or update is complete, the "Gatekeeper" parameter can be changed back to its previous value. No further changes are required, not even after a restart of the machine.
