In the last six months, online platforms filed more than 4.4 billion content moderation decisions with the European Commission. That is the running total on the DSA Transparency Database, where every platform covered by the EU’s Digital Services Act must log a “statement of reasons” each time it removes, demotes or restricts something a user posted. Behind a large share of those decisions sits a person working for one of the content moderation services on this list, reading a policy document and deciding whether a post, an image or a chatbot reply crosses the line.
Outsourced content moderation used to mean a room of reviewers clearing a social media queue. The work has widened. Marketplaces screen listings for scams, dating apps check profiles, game studios watch voice chat, and AI labs now need people to judge model outputs for harm before anyone outside the company sees them. The content moderation companies below cover that whole range, from global trust and safety operations with thousands of reviewers to specialists that do one thing well. We start with our own pick for AI safety work.

1. Zilo AI
Zilo AI is a staffing and data annotation company in Bangalore, and its moderation work is pointed at a newer problem than spam in a comments section: keeping AI models safe. Through its data annotation and AI evaluation services, Zilo supplies content moderators who review user prompts and AI-generated text and images against a client’s safety policy, label toxicity and bias, and follow escalation workflows. The same teams include AI response raters who score chatbot answers for safety and quality, and red-teamers who probe models with adversarial prompts and jailbreak attempts so that refusal and safety-tuning datasets can be built from what breaks.
Zilo says it has more than 1,600 trained annotation and ASR experts, has annotated over 10 million data points for industries from retail to BFSI to healthcare, and works in about 26 languages. Engagements run as managed projects, pilot batches, dedicated teams or straight annotator staffing, so a team can start with a small batch and grow it once the guidelines are settled.
Best for: AI companies and product teams that need human safety review of model outputs, or moderators placed on contract inside their own trust and safety function.
What to check: Zilo is not a 24/7 social media moderation center with its own wellness program on the scale of the largest BPOs. If your need is round-the-clock review of a consumer feed, ask how shifts, wellness support and escalation would be staffed before you sign.
2. TaskUs
TaskUs is one of the best known outsourced content moderation providers, and trust and safety is a headline service rather than an add-on. The company also runs AI safety and alignment work, AI data operations and customer experience, with sites in 14 countries. Its trust and safety practice is paired with a wellness and resiliency offering, which matters in a job where reviewers spend the day looking at material most people never see.
Best for: large social, gaming and marketplace platforms with high daily volumes and a need for teams across time zones.
What to check: minimum team sizes and contract length. Providers built for big platforms often want a commitment that a startup cannot make.
3. TP (Teleperformance)
TP, the company long known as Teleperformance, is one of the largest outsourcing groups in the world, and it bought the European provider Majorel. Its trust and safety line describes AI-enabled moderation, fraud prevention and risk controls for users, platforms and brands. Because TP also runs customer care for many of the same clients, it can keep moderation and support on one contract.
Best for: enterprises that want moderation in many languages and countries, run by a supplier that can also handle their contact center.
What to check: which delivery sites and languages would serve your account, and whether the moderators would be dedicated to you or shared across clients.
4. TELUS Digital
TELUS Digital, part of the Canadian telecom group TELUS, sells contact center outsourcing, AI training data and a trust and safety practice. Its platform integrity line covers content moderation solutions and age assurance, and its wider trust and safety work includes fraud prevention and ID verification. That combination suits platforms that face age and identity rules as well as harmful content.
Best for: platforms that need content moderation, age checks and identity verification from a single provider.
What to check: how its AI tools and human reviewers split the work on your content type, and who owns the policy decisions when the two disagree.
5. Concentrix
Concentrix is a global customer experience company that lists trust and safety under its enterprise protection services, framed around resilience, governance and compliance. Its strength is breadth: a company already using Concentrix for customer support can add moderation without onboarding a new vendor,.
Best for: existing Concentrix clients, and large brands that want trust and safety managed alongside customer care.
What to check: its homepage speaks about trust and safety in broad terms, so ask for specifics on content types, review tooling and accuracy reporting for your use case.
6. Besedo
Besedo has done one thing since it started in Stockholm in 2002, which is content moderation. It pairs AI with human moderators to catch spam, fraud, scams and harmful user content in real time, and clients can outsource moderation entirely or keep part of it in house. Marketplaces, classifieds and dating sites are its natural ground, where a fake listing or a romance scam does more damage than an offensive comment.
Best for: online marketplaces, classifieds and dating platforms that need fraud-aware moderation.
What to check: its language coverage for your markets, and how quickly its models can be tuned when a new scam pattern appears.
7. ModSquad
ModSquad calls itself a business operations provider, and its trust and safety practice covers content moderation, community management and social operations, with AI assisting human judgment. Community work is central to the offer, which helps with moderation where the slang, memes and in-jokes of a fan base can fool a generic reviewer.
Best for: gaming studios, fan communities and consumer brands with active social channels.
What to check: whether you need moderation only, or community management too, because the second is a different skill and priced differently.
8. IntouchCX (with WebPurify)
WebPurify built its name on image, video and text moderation that combined AI filters with human reviewers around the clock. It is now part of IntouchCX, a customer experience company whose trust and safety service covers AI and human-led moderation, real-time content review, fraud detection and misinformation prevention. Buyers who knew WebPurify will find its moderation work inside the IntouchCX trust and safety offer.
Best for: companies that need visual content reviewed quickly, including live streams, and want a provider that also runs customer support.
What to check: how the WebPurify tools and teams fit into IntouchCX today, and which contract you would sign.
9. Enshored
Enshored builds outsourced teams for growing companies, with content moderation as one of its solutions alongside customer service, sales support and back office work. Its pitch is a dedicated team that maintains a safe space for your users, working across time zones and in many languages.
Best for: startups and scale-ups that want a named team of moderators rather than a slice of a shared pool.
What to check: where the team will sit and how the provider handles wellness for moderators who see distressing content.
10. Cogito Tech
Cogito Tech is a New York based company that curates and labels training data for computer vision, language and generative AI models, and it also moderates user-generated content for social media, forums, gaming, dating, marketplaces and children’s websites. It makes sense when the same reviewed content will later be used to train a classifier.
Best for: teams that want UGC moderation and AI training data from one vendor.
What to check: turnaround times for live moderation, since data labeling work often runs on batch schedules rather than minute-by-minute queues.
11. AnnotationBox
AnnotationBox is a data labeling company with offices in Kolkata, Florida and London. Its content moderation service covers sentiment analysis, explicit material detection, spam filtering and flagging offensive content, with human reviewers in the loop.
Best for: small and mid-sized platforms that need affordable review of images and text.
What to check: capacity for sudden spikes, and whether reviewers are trained on your policy or on a generic one.
How to choose a content moderation service
Start with the content, not the vendor. A feed of short text comments, a marketplace full of product photos and a chatbot that writes its own answers are three different jobs, and the providers above are strongest in different places. Write down what your users post, how fast a decision must be made, and which languages they post in. That short document will rule out half the list.
Then look at how the provider splits work between machines and people. Almost every company here uses AI filters for the obvious cases and human reviewers for the judgment calls. Ask what share of your volume would reach a human, how disagreements are resolved, and how the provider reports accuracy. If you operate in the EU, ask how decisions are documented, because the Digital Services Act expects a reason for each one.
Wellness is not a soft question. Moderators who review violent or abusive material burn out, and burnt-out reviewers make worse decisions. Ask for the provider’s exposure limits, counselling access and rotation policy, and ask to speak to a team lead.
Finally, run a pilot. Give two shortlisted providers the same sample, the same policy and the same deadline, and compare their decisions against your own team’s. For AI safety review, red-teaming or moderators placed on contract inside your team, talk to Zilo AI about a pilot batch.
Frequently asked questions
What are content moderation services?
Content moderation services are outsourced teams, software or both that review what users post on a platform and remove, restrict or allow it according to the platform’s rules. Most providers combine automated filters with human reviewers who handle the cases a machine cannot judge.
Why do companies outsource content moderation?
Mostly for coverage. Outsourced content moderation lets a platform cover every time zone and language its users write in without building a large in-house team, and specialist providers bring trained reviewers, tooling and wellness programs that are expensive to build from scratch.
What is the difference between content moderation and trust and safety?
Content moderation is the act of reviewing posts, images and videos. Trust and safety is the wider function that writes the policies, fights fraud, verifies identities and handles regulators. Many content moderation companies now sell both under the trust and safety label.
Do AI models need content moderation too?
Yes. AI companies use human raters to judge whether model outputs are harmful, biased or unsafe, and red-teamers to find prompts that make a model misbehave. Zilo AI and TaskUs both offer this kind of AI safety work.
How should I compare content moderation companies?
Compare them on your own content. Ask each shortlisted provider for a paid pilot on a real sample, measure accuracy and speed against your internal decisions, and check language coverage, reviewer wellness policies and how decisions are logged for regulators.
