Making a good machine learning model involves more than just good data and well-selected features. Each model also has its own set of hyperparameters, variables which are set before training begins to influence how a given model learns. In this article, we go over grid search, a technique used to select the best hyperparameters for a model quickly and efficiently!

Solution Spotlight
Integrated Email Security
Our integrated email protection prevents sophisticated attacks that evade the built-in capabilities of the cloud providers.
RetroHunt
Proactively hunt for threat actors that initially evaded your defenses, reduce their dwell time and eliminate their foothold.
Breach and Attack Simulation
Identify gaps in your existing email security controls and coverage by simulating attacks that leverage emerging malware threats.
Why InQuest?
File Analysis at Scale
Ingestion and dissection of tens of millions of files daily leveraging a combination of our Deep File Inspection (DFI) analysis engine and our proprietary machine learning apparatus.
Zero-Day Attack Coverage
Mitigation of attacks targeting publicly unknown vulnerabilities that affect a wide array of commonly used software solutions.
Eradicate BEC, Malware and Ransomware Attacks
Our cloud-based integrated email security solution, leveraging our patented Deep File Inspection (DFI), goes to unparalleled levels of scrutiny to analyze, identify, and ultimately prevent malware, phishing, ransomware, spam and scams from being delivered to your users.
Operationalize Your Threat Intelligence
Leverage our platform to operationalize machine readable threat intelligence (MRTI) information at scale and tag your data as it flows through your environment.
Continuous Threat Hunting via RetroHunting
Through the use of RetroHunting, we provide you with the ability to proactively hunt for threats related to advanced targeted attacks that may have initially bypassed your real-time defenses. This answers the question of "Was this new attack or technique successful in bypassing our security defenses?"
Intelligent Orchestration
We aim to automate and scale the expert knowledge of a SOC analyst. Our platform leverages a variety of sources in an automated decision-making engine that includes bi-directional orchestration with multi-scanning and sandbox solutions, unique threat intelligence sources and a seasoned research team augmented by a variety of machine learning models.
Machine Learning Assisted Threat Prevention
Our proprietary machine learning software is built out of four well-vetted classifiers and uses previously collected data on malicious and benign content to automatically discover patterns that might be left uncovered by signatures. On a weekly basis, models constructed from our ML algorithms are updated with the latest information from previously processed network traffic.
SIEM Data Enrichment
Enhance your security posture and maximize the investment you've made on your existing security infrastructure by expanding your Indicators of Compromise (IOCs) and overlaying our machine readable threat intelligence (MRTI) information on top of your alerts, logs, etc. Efficiently and effectively surface malware activity from your security tools that may have gone undetected for weeks or even month in the past.
Tailored Threat Intelligence
Our tailored intelligence offering monitors the clear, deep and dark web for information directly pertaining to your organization and provides actionable intelligence specific to the risks and threats specifically associated with your assets.
Sandbox Offloading and Optimization
Large scale dynamic analysis through the use of sandbox detonation is a resource intensive and time-consuming operation. Offset the load on your dynamic analysis solutions by leveraging our static analysis platform and achieve accelerated threat detection at scale leaving only the most critical files of interest for runtime analysis.

Latest Event
We launched InQuest Labs (labs.inquest.net) in August of 2019, as a way to publicly demo some of our research and development and to empower researchers interested in discovering novel/exemplar document borne malware. Unveiled at Black Hat 2019, InQuest Labs made a splash with the availability of a free (as in beer) aggregate reputation feed, communal IOC harvesting, tools for YARA developers, and a light version of our Deep File Inspection (DFI) engine.
Latest White Paper
Data Loss Discovery Driven by Deep File Inspection (DFI™)
The purpose of this whitepaper is to describe the capabilities provided by the InQuest platform related to identifying the exposure of sensitive information. With the recent explosion of data breach reports in the news, preventing the loss of sensitive data has become an area of focus for many organizations.
Here's what our customers are saying
Prior to having InQuest, file decompression, decoding and post-processing were all manual steps that were very time consuming for us. Now that we're using InQuest, all of those steps are automated and it has given us the ability to apply these steps to not only files we think are suspicious, but all files received by our users.
Having the ability to search historically based on file content is like having our own internal VirusTotal Retrohunt.
The threat score calculation and assignment being performed by InQuest's engine makes it easy for us to sift through the legitimate sessions and focus on the real threats targeting our users.
InQuest provides a complete network forensics picture, from session details such as header information to file details such as the hash, size, type and even the raw file.
The data loss prevention coverage InQuest provides for data-in-transit is second to none.
The InQuest platform is unlike any other network-based security system we've seen. The performance of their native capture engine and analytic capabilities are unparalleled in terms of the throughput it can support and the number of files it can dissect and analyze.
The third-party integrations with multiav and sandbox solutions are seamless. We have never had a security platform that made it so easy to automate all of our static and dynamic file analysis efforts.
Over half of our customer’s traffic is encrypted and InQuest is the first security platform we’ve seen with a specific focus on using SSL related indicators of compromise to detect the bad guy’s infrastructure.
The threat intelligence InQuest is able to gather and disseminate via their reputation and threat feeds has alerted us to numerous customer compromises. They are truly at the cutting edge when it comes to identifying threat actor infrastructure as it is deployed.
It’s pretty amazing that they are able to support capturing, reassembling, processing, storing and inspecting content at speeds over 20Gb without dropping traffic all in a 1U box.
We’ve been customers for several years now and up until the recent acquisition of their appliances we were running their collectors on 4U boxes with flash storage cards. As a result of that acquisition, we went from having to deal with three different vendors to one vendor, reduced our rackspace footprint as well as our power consumption which all resulted in a huge cost savings for us. Kudos to InQuest!
Through their data orchestration and workflow, they’ve made it really easy for us to establish repeatable workflows from within their UI. That has saved our SOC analysts a considerable amount of time and has enabled them to pivot through data from numerous systems all from a single pane of glass.
Earlier this year, our friends at Abuse.ch officially announced in a tweet that their MalwareBazaar project was integrated with InQuest’s Deep File Inspection (DFI) analysis stack.
Some of you may have seen our analysis on MalwareBazaar already and even may have observed a link back to our own analysis platform. Looking at one of the latest files on MalwareBazaar, we found an excellent example that will familiarize and clarify the significance of this integration. Here is a recent sample for those not yet familiar with either platform
Take a look at some of the MalwareBazaar Samples on InQuest Labs!
